这里的File是控件的IDstring FileName = File.FileName;//获取上传文件的名称
string Str = FileName.Split(\'.\')[1];//获取上传文件的后缀
string NewName = DateTime.Now.ToString("yyyyMMddhhmmss")+"."+Str;//重命名上传文件
string FilePath = Server.MapPath("~/Image/");//设置上传文件的保存路径
if (!Directory.Exists(FilePath))//判断路径是否存在
Directory.CreateDirectory(FilePath);//如果不存在创建文件夹
File.SaveAs(FilePath + NewName);//上传文件 参考技术A string m_sUpFilePath = Server.MapPath("../" + "UpFiles/UpFile/");
string m_sFileName = DateTime.Now.ToString("yyyyMMddHHmmss") + DateTime.Now.Millisecond.ToString();
HttpFileCollection m_hfcPro = Request.Files;
HttpPostedFile myFile = m_hfcPro[0];
string savename = m_sFileName + Path.GetExtension(this.downUrl.FileName).ToLower();
m_sFileName = m_sUpFilePath + @"\" + m_sFileName;
if (downUrl.FileName.HasFile )
if (this.downUrl.HasFile && (Path.GetExtension(this.downUrl.FileName).ToLower() != ".jpg" || Path.GetExtension(this.downUrl.FileName) != ".gif" || Path.GetExtension(this.downUrl.FileName) != ".png") && Common.Left(this.downUrl.PostedFile.ContentType, 5).ToLower() == "image")
SqlConnection m_conAdd = Common.CreateConn();
m_conAdd.Open();
SqlCommand m_comAdd = new SqlCommand("Insert Into weblink(SiteName,LinkUrl,LinkLogo,OrderID,IsCheck,IsMain,Notes)Values(@sitename,@linkurl,@linklogo,@orderid,@ischeck,@ismain,@notes)", m_conAdd);
m_comAdd.Parameters.Add("@sitename", SqlDbType.VarChar, 200).Value = this.siteName.Text;
m_comAdd.Parameters.Add("@linkurl", SqlDbType.VarChar, 100).Value = this.siteLink.Text;
m_comAdd.Parameters.Add("@linklogo", SqlDbType.VarChar, 100).Value = savename;
m_comAdd.Parameters.Add("@orderid", SqlDbType.Int).Value = (this.siteOrder.Text.Trim() != "" ? Convert.ToInt32(this.siteOrder.Text) : 21);
m_comAdd.Parameters.Add("@ischeck", SqlDbType.Int).Value = 0;
m_comAdd.Parameters.Add("@ismain", SqlDbType.Int).Value = 0;
m_comAdd.Parameters.Add("@notes", SqlDbType.VarChar, 1000).Value = Common.CutString(this.siteNotes.Text, 1000);
m_comAdd.ExecuteNonQuery();
m_comAdd.Dispose();
m_conAdd.Close();
m_conAdd.Dispose();
this.downUrl.SaveAs(m_sUpFilePath + savename);
else
Common.Alert("上传文件格式不正确");
