這篇文章主要介紹了C# 實現(xiàn)FTP上傳資料的示例，幫助大家更好的理解和學習c#，感興趣的朋友可以了解下

1.通過用FTP進行上傳文件，首先要實現(xiàn)建立FTP連接，一般建立FTP連接，需要知道FTP配置有關的信息。一般要在Bean中建立一個ServiceFileInfo.cs文件進行記錄，一般需要FTP地址、登錄用戶名和登錄密碼。然后通過其他頁面進行訪問讀取。代碼樣式如下：

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.通過主方法讀取Bean文件下面的的ServiceFileInfo.cs文件的信息，去實現(xiàn)建立FTP連接。這里還需要清楚的知道你上傳文件的路徑(Path)和文件名稱(FileName)。根據(jù)這些信息主方法去調用寫著Bean中的另外一個ftpOperation.cs 文件(這個.cs文件中主要寫一些關于FTP的操作方法)，進行FTP訪問操作。

主方法調用FTP操作代碼

ExecutionResult exeRes = this.ftpOperation.UploadFile(textFilePath, txtUID, txtPWD, Path + "/" + FileName + ".txt");//.txt為文件的后綴名

Bean文件中ftpOperation.cs文件關于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);//調用下面代碼方法
      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("非法文件名或目錄名!");
        }
        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("非法文件名或目錄名!");
      }
      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服務上面已經存在同名文件！");
        }
        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;
    }
