【中文标题】访问路径“Enrollments.zip”被拒绝，运行后台服务运行后【英文标题】：Access to the path 'Enrollments.zip' is denied, After running Background service running 【发布时间】：2018-10-24 06:12:44 【问题描述】：重启电脑后，后台服务正常。如果我重新安装或对数据库进行了任何更改，我的 PC 访问路径“.zip”被拒绝。另一台 PC 上正在运行相同背景的另一件事。
两个后台服务在两台不同的 PC 上运行以交换数据。
代码如下：
public void GetFilesFromWebAPIAndCountTemplates(DateTime startTime,DateTime endTime,string webAPIURL,string code,string localPath)
ZipLocationsCount zipLocation = null;
count = 0;
if (startTime < endTime)
WebApiCall apiCall = new WebApiCall();
Thread.Sleep(10000);
var zipByteResponse = apiCall.CallZipWebApi(webAPIURL, "api/ZIPEnrollmentsDownload/ZIPResponse?startTime=" + startTime + "&endTime=" + endTime+ "&locationCode="+code, null, Constants.Get);
lgmr.Log(string.Concat(serviceName, " ", code, ": Get Response From WebAPI successfully"), LoggingManager.LogType.Info);
if (zipByteResponse.Result != null && zipByteResponse.Result.Length > 0)
string fileName = code + "_Enrollments.zip";
try
ConvertIntoZipAndMoveToBackUp(localPath, fileName, zipByteResponse.Result, code);
catch(Exception ex)
//GetFilesFromWebAPIAndCountTemplates(startTime, endTime, webAPIURL, code, localPath);
ecount = 0;
strECount = "Fail to Zip";
lgmr.Log(string.Concat(serviceName, " ", code, " count:", ecount, ": Failed to Converted to ZIP", ex.StackTrace, ex.InnerException, ex.Message), LoggingManager.LogType.Error);
goto label1;
else
ecount = 0;
if(ecount == 0)
strECount = "No Enrolments";
lgmr.Log(string.Concat(serviceName, " ", code, ": No Enrollments"), LoggingManager.LogType.Info);
else
lgmr.Log(string.Concat(serviceName, " ",code, ": Start Date Should be lass than End Date"), LoggingManager.LogType.Info);
FPSyncHistory fpSync = new FPSyncHistory();
fpSync.LocationCode = code;
fpSync.FromDate = startTime;
fpSync.ToDate = endTime;
fpSync.FPExported = ecount;
fpSync.Status = true;
fpSync.CreatedBy = 1;
fpSync.CreatedOn = DateTime.Now;
fPSyncHistories.Add(fpSync);
label1:
zipLocation = new ZipLocationsCount() LocationCode = code, FromDate = startTime, ToDate = endTime, EnrollmentsCount = strECount ;
if (zipLocation.FromDate < zipLocation.ToDate)
zipLocationsCounts.Add(zipLocation);
上面的方法我正在调用另一个方法
public void GetZipResponseFromWebAPI()
try
zipLocationsCounts = new List<ZipLocationsCount>();
fPSyncHistories = new List<FPSyncHistory>();
DateTime sTime = new DateTime();
DateTime startTime = new DateTime();
DateTime eTime = new DateTime();
DateTime endTime = new DateTime();
foreach (FPSyncLocationDetail fpLocation in tmlEntity.FPSyncLocationDetails)
var findHistory = tmlEntity.FPSyncHistories.FirstOrDefault(x => x.LocationCode == fpLocation.Code);
if (findHistory == null)
if(fpLocation.Status == true)
sTime = DateTime.Now.AddDays(-1);
startTime = new DateTime(sTime.Year, sTime.Month, sTime.Day, 00, 00, 00);
eTime = DateTime.Now.AddDays(-1);
endTime = new DateTime(eTime.Year, eTime.Month, eTime.Day, 23, 59, 59);
GetFilesFromWebAPIAndCountTemplates(startTime,endTime,fpLocation.WebAPIURL,fpLocation.Code,fpLocation.LocalFPFolderPath);
else if (findHistory != null)
var locationLastDates = from n in tmlEntity.FPSyncHistories
group n by n.LocationCode into g
select new LocationCode = g.Key, ToDate = g.Max(t => t.ToDate) ;
foreach (var loc in locationLastDates)
if (fpLocation.Code == loc.LocationCode)
if (fpLocation.Status == true)
sTime = loc.ToDate.AddDays(1);
startTime = new DateTime(sTime.Year, sTime.Month, sTime.Day, 00, 00, 00);
eTime = DateTime.Now.AddDays(-1);
endTime = new DateTime(eTime.Year, eTime.Month, eTime.Day, 23, 59, 59);
GetFilesFromWebAPIAndCountTemplates(startTime, endTime, fpLocation.WebAPIURL, fpLocation.Code, fpLocation.LocalFPFolderPath);
catch (Exception ex)
string InnerException = ex.InnerException != null ? ex.InnerException.ToString() : "";
lgmr.Log(string.Concat("Error at GetZipResponseFromWebAPI", ex.StackTrace, ex.InnerException, ex.Message), LoggingManager.LogType.Error);
return;
下面终于CallWebAPI方法逻辑了
public async Task<byte[]> CallZipWebApi(String WebApiUri, String uri, StringContent obj, string type)
try
count++;
HttpResponseMessage resMeg;
using (var client = new HttpClient())
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/octet-stream"));
client.BaseAddress = new Uri(WebApiUri);
lgmr.Log(string.Concat(uri,": Sending Request to WebAPI"), LoggingManager.LogType.Info);
if (type == Constants.Get)
resMeg =await client.GetAsync(uri);
else
resMeg =await client.PostAsync(uri, obj);
lgmr.Log(string.Concat(uri,": Receive Response From WebAPI"), LoggingManager.LogType.Info);
var Bytes =await resMeg.Content.ReadAsByteArrayAsync();
//byte[] mybyteArray = null;
//Task<byte[]> Bytes = ProcessURLAsync(uri,client);
lgmr.Log(string.Concat(": Read the Data from WebAPI Response"), LoggingManager.LogType.Info);
return Bytes;
public void ConvertIntoZipAndMoveToBackUp(string localPath, string fileName, byte[] zipByteResponse, string code)
string Destinationpath = ConfigurationManager.AppSettings["OtherEnrollmentsBackUpPath"] + "\\" + code;
try
ZipArchive archive = null;
if (File.Exists(localPath + "\\" + fileName))
File.Delete(localPath + "\\" + fileName);
archive = ZipFile.Open(localPath + "\\" + fileName, ZipArchiveMode.Create);
archive.Dispose();
lgmr.Log(string.Concat(serviceName, " ", code, ": Zip File Created", localPath + "\\" + fileName), LoggingManager.LogType.Info);
File.WriteAllBytes(localPath + "\\" + fileName, zipByteResponse);
lgmr.Log(string.Concat(serviceName, " ", code, ": Download Zipfile from the WebAPI Response"), LoggingManager.LogType.Info);
archive = ZipFile.OpenRead(localPath + "\\" + fileName);
ecount = archive.Entries.Count(x => !string.IsNullOrWhiteSpace(x.Name));
strECount = ecount.ToString();
lgmr.Log(string.Concat(serviceName, " ", code, ": Files Count: ",ecount, localPath + "\\" + fileName), LoggingManager.LogType.Info);
foreach (ZipArchiveEntry entry in archive.Entries)
if (File.Exists(localPath + "\\" + entry.Name))
File.Delete(localPath + "\\" + entry.Name);
entry.ExtractToFile(localPath + "\\" + entry.Name);
archive.Dispose();
File.Move(localPath + "\\" + fileName, Destinationpath + "\\" + code + string.Format("Enrollments-0:yyyy-MM-dd_hh-mm-ss.fff.zip", DateTime.Now));
catch (Exception ex)
//File.Delete(localPath + "\\" + fileName);
//File.Move(localPath + "\\" + fileName, Destinationpath + "\\" + code + string.Format("ZipErrorEnrollments-0:yyyy-MM-dd_hh-mm-ss.fff.zip", DateTime.Now));
ecount = 0;
lgmr.Log(string.Concat(serviceName, " ", code, " ECount:", ecount, ": Failed to ZIP", localPath + "\\" + fileName, "Resend the Request to WebAPI ", ex.Message), LoggingManager.LogType.Info);
throw ex;
【问题讨论】：
【参考方案1】：一些你可以看的东西。
首先，使用using 语句创建存档，这将确保它被处理掉。
其次，你为什么要检查文件是否存在，删除它，然后用ZipFile创建它只是为了用File写它？看this
第三，使用 Path 类。它将确保您所有的反斜杠都是正确的，并且看起来更整洁。
四、检查文件夹中是否可以创建文件
检查这段代码是否给你同样的结果。
public void ConvertIntoZipAndMoveToBackUp(string localPath, string fileName, byte[] zipByteResponse, string code)
string Destinationpath = Path.Combine(ConfigurationManager.AppSettings["OtherEnrollmentsBackUpPath"], code);
try
fileName = Path.GetFileNameWithoutExtension(fileName) + DateTime.Now.ToString("yyyy-MM-dd_hh-mm-ss.fff") + ".zip"; //This will ensure that you have a unique filename to create
File.WriteAllBytes(Path.Combine(localPath, fileName), zipByteResponse);
lgmr.Log(string.Concat(serviceName, " ", code, ": Zip File Created and Downloaded from the WebAPI Response", Path.Combine(localPath, fileName)), LoggingManager.LogType.Info);
using (var archive = ZipFile.OpenRead(Path.Combine(localPath, fileName)))
ecount = archive.Entries.Count(x => !string.IsNullOrWhiteSpace(x.Name));
strECount = ecount.ToString();
lgmr.Log(string.Concat(serviceName, " ", code, ": Files Count: ",ecount, localPath + "\\" + fileName), LoggingManager.LogType.Info);
foreach (ZipArchiveEntry entry in archive.Entries)
if (File.Exists(Path.Combine(localPath, entry.Name)))
File.Delete(Path.Combine(localPath, entry.Name));
entry.ExtractToFile(Path.Combine(localPath, entry.Name));
File.Move(Path.Combine(localPath, fileName), Path.Combine(Destinationpath, code + string.Format("Enrollments-0:yyyy-MM-dd_hh-mm-ss.fff.zip", DateTime.Now)));
catch (Exception ex)
//File.Delete(localPath + "\\" + fileName);
//File.Move(localPath + "\\" + fileName, Destinationpath + "\\" + code + string.Format("ZipErrorEnrollments-0:yyyy-MM-dd_hh-mm-ss.fff.zip", DateTime.Now));
ecount = 0;
lgmr.Log(string.Concat(serviceName, " ", code, " ECount:", ecount, ": Failed to ZIP", localPath + "\\" + fileName, "Resend the Request to WebAPI ", ex.Message), LoggingManager.LogType.Info);
throw ex;
【讨论】：
您可能不必重新启动 PC。只需重新启动服务。你能在调试中运行它吗？ File.WriteAllBytes(Path.Combine(localPath, fileName), zipByteResponse); // 这里又是异常， 第一次成功运行后，能否检查文件是否真的被移动了。因为你会得到这个错误的唯一原因是文件没有被移动，你尝试创建相同的文件 如何检查文件是否被移动？ 重启电脑后，后台服务正常。第二次起同样的例外。文件夹内没有“.zip”文件以上是关于访问路径“Enrollments.zip”被拒绝，运行后台服务运行后的主要内容，如果未能解决你的问题，请参考以下文章
