Posted 2021-12-29 qiu18359243869

今天在winform上需要上传，删除服务器上的文件，网上找了下上传是很多，可删除没有找到答案，，最后只能拿个土办法实现了，这里是用ashx文件来处理
上传：
B/S
 
 public void ProcessRequest(HttpContext context)
       
            foreach (string fileKey in context.Request.Files)
           
                try
               
                    HttpPostedFile file = context.Request.Files[fileKey];
                    string oldFileName = file.FileName; //原文件名  xxx.jpg
                    int extenIndex = oldFileName.LastIndexOf(".");
                    string getExtent = oldFileName.Substring(extenIndex);//文件扩展名  .jpg
                    string fileSize = UploadCommon.getFileSize(file.ContentLength);  //获取文件大小 
                    string newFileName = DateTime.Now.ToString("yyyyMMddHHmmssms") + (new Random()).Next(0, 9) + getExtent;
                    string path = "/AffixFiles/sw_Products/";
                    if (!Directory.Exists(context.Server.MapPath(path)))
                   
                        Directory.CreateDirectory(context.Server.MapPath(path));
                   
                    string filePath = Path.Combine(path, newFileName);//文件相对路径
                    file.SaveAs(context.Server.MapPath(filePath));
                    string json = "\"status\":\"success\",\"oldFileName\":\"" + oldFileName + "\",\"fileSize\":\"" + fileSize + "\",\"filePath\":\"" + filePath + "\",\"fileType\":\"" + getExtent + "\"";
                    context.Response.Write(json);
               
                catch
               
                    string json = "\"status\":\"error\",\"oldFileName\":\"" + null + "\",\"fileSize\":\"" + null + "\",\"filePath\":\"" + null + "\",\"fileType\":\"" + null + "\"";
                    context.Response.Write(json);
               
                context.Response.End();
           
       
C/S
 
private void 上传_Click(object sender, EventArgs e)
       
            System.Net.WebClient myWebClient = new System.Net.WebClient();
            byte[] b = myWebClient.UploadFile("http://190.160.10.13:8088/ClientUpload/ClientUploadTools.ashx",
                "POST", "C:\\1351040562_Download.png");
        
           string returnJson = Encoding.Default.GetString(b);
           javascriptSerializer json = new JavaScriptSerializer();
           uploadMessage result = json.Deserialize<uploadMessage>(returnJson);//最后的返回结果集
           
       
        public class uploadMessage
       
            public string oldFileName get; set;
            public string fileSize get; set;
            public string filePath get; set;
            public string fileType get; set;
            public string status get; set;
       
 
 
删除：
这里删除就使用了 UploadData方法来处理，太土了，大家有没有更好的办法提供一下哈
B/S
 
 public void ProcessRequest(HttpContext context)
       
            try
           
                int totalBytes = context.Request.TotalBytes;
                if (totalBytes > 0)
               
                    byte[] readBytes = context.Request.BinaryRead(totalBytes);
                    string filePath = System.Text.Encoding.Default.GetString(readBytes);
                    string overFile = context.Server.MapPath(filePath);
                    if (File.Exists(overFile))
                   
                        try
                       
                            File.Delete(overFile);
                            context.Response.Write("success");
                       
                        catch
                       
                            context.Response.Write("error");
                       
                   
               
           
            catch
           
                context.Response.Write("error");
           
            context.Response.End();
       
 
C/S
 
/// <summary>
        /// 删除成功success  删除失败 error
        /// </summary>
        private void 删除_Click(object sender, EventArgs e)
       
            System.Net.WebClient myWebClient = new System.Net.WebClient();
            byte[] b = myWebClient.UploadData("http://localhost:2666/ClientUpload/ClientDeleteTool.ashx",
                "POST", Encoding.Default.GetBytes("/AffixFiles/sw_Products/2012112211243824388.png"));
            string result = Encoding.Default.GetString(b);//返回的结果
