1.通过用FTP进行上传文件，首先要实现建立FTP连接，一般建立FTP连接，需要知道FTP配置有关的信息。一般要在Bean中建立一个ServiceFileInfo.cs文件进行记录，一般需要FTP地址、登录用户名和登录密码。然后通过其他页面进行访问读取。代码样式如下：

class ServiceFileInfo     {         // service1         public static string txtFilePath = @"ftp://12.128.128.01/FileName/";         //userid & password         public static string txtUID = "username";         public static string txtPWD = "password";     }

2.通过主方法读取Bean文件下面的的ServiceFileInfo.cs文件的信息，去实现建立FTP连接。这里还需要清楚的知道你上传文件的路径(Path)和文件名称(FileName)。根据这些信息主方法去调用写着Bean中的另外一个ftpOperation.cs 文件(这个.cs文件中主要写一些关于FTP的操作方法)，进行FTP访问操作。

• 主方法调用FTP操作代码

ExecutionResult exeRes = this.ftpOperation.UploadFile(textFilePath, txtUID, txtPWD, Path + "/" + FileName + ".txt");//.txt为文件的后缀名

•  Bean文件中ftpOperation.cs文件关于FTP操作的方法

public ExecutionResult UploadFile(string vIMSPath, string vUID, string vPassword, string vLocalPath)         {             ExecutionResult result = new ExecutionResult();             result = connectState(vIMSPath, vUID, vPassword, vLocalPath);//调用下面代码方法             if (result.Status)             {                 File.Delete(vLocalPath);             }             return result;         }

connectState()方法

public static ExecutionResult connectState(string vIMSPath, string vUID, string vPassword, string fileName)         {             string operater = "";             bool Flag = false;             ExecutionResult result;             result = new ExecutionResult();             lock (lockObj)             {                 try                 {                     operater = "Connet to FTP";                     FTPOperation ftp = new FTPOperation(new Uri(vIMSPath), vUID, vPassword);                     operater = "Upload file";                     Flag = ftp.UploadFile(fileName, Path.GetFileName(fileName), true);                     if (Flag)                     {                         result.Status = true;                         result.Message = "Send to server OK";                     }                 }                 catch (Exception ex)                 {                     result.Status = false;                     result.Anything = "Mail";                     result.Message = operater + ":" + ex.Message;                 }             }             return result;         }

• UploadFile()方法

public bool UploadFile(string LocalFullPath, string RemoteFileName, bool OverWriteRemoteFile)         {             bool result;             try             {                 bool flag = !this.IsValidFileChars(RemoteFileName) || !this.IsValidFileChars(Path.GetFileName(LocalFullPath)) || !this.IsValidPathChars(Path.GetDirectoryName(LocalFullPath));                 if (flag)                 {                     throw new Exception("非法文件名或目录名!");                 }                 bool flag2 = File.Exists(LocalFullPath);                 if (!flag2)                 {                     throw new Exception("本地文件不存在!");                 }                 FileStream fileStream = new FileStream(LocalFullPath, FileMode.Open, FileAccess.Read);                 byte[] array = new byte[fileStream.Length];                 fileStream.Read(array, 0, (int)fileStream.Length);                 fileStream.Close();                 result = this.UploadFile(array, RemoteFileName, OverWriteRemoteFile);             }             catch (Exception ex)             {                 this.ErrorMsg = ex.ToString();                 throw ex;             }             return result;         } public bool UploadFile(byte[] FileBytes, string RemoteFileName)         {             bool flag = !this.IsValidFileChars(RemoteFileName);             if (flag)             {                 throw new Exception("非法文件名或目录名!");             }             return this.UploadFile(FileBytes, RemoteFileName, false);         } public bool UploadFile(byte[] FileBytes, string RemoteFileName, bool OverWriteRemoteFile)         {             bool result;             try             {                 bool flag = !this.IsValidFileChars(RemoteFileName);                 if (flag)                 {                     throw new Exception("非法文件名！");                 }                 bool flag2 = !OverWriteRemoteFile && this.FileExist(RemoteFileName);                 if (flag2)                 {                     throw new Exception("FTP服务上面已经存在同名文件！");                 }                 this.Response = this.Open(new Uri(this.Uri.ToString() + RemoteFileName), "STOR");                 Stream requestStream = this.Request.GetRequestStream();                 MemoryStream memoryStream = new MemoryStream(FileBytes);                 byte[] array = new byte[1024];                 int num = 0;                 for (;;)                 {                     int num2 = memoryStream.Read(array, 0, array.Length);                     bool flag3 = num2 == 0;                     if (flag3)                     {                         break;                     }                     num += num2;                     requestStream.Write(array, 0, num2);                 }                 requestStream.Close();                 this.Response = (FtpWebResponse)this.Request.GetResponse();                 memoryStream.Close();                 memoryStream.Dispose();                 FileBytes = null;                 result = true;             }             catch (Exception ex)             {                 this.ErrorMsg = ex.ToString();                 throw ex;             }             return result;         }
