WinSCP SFTP - .tmp该进程无法访问该文件

Question

我正在尝试使用以下代码上传文件,但在下面收到错误.

一些注意事项:我正在使用Windows 7.使用CrushFTP SFTP服务器,能够使用FileZilla和WinSCP客户端连接,但通过代码它是噩梦.

错误/例外:

mscorlib.dll中发生了'System.IO.IOException'类型的第一次机会异常

附加信息:进程无法访问文件'C:\ Users\xxxxxxx\AppData\Local\Temp\wscp0D64.036B20B7.tmp',因为它正由另一个进程使用.

我的连接代码如下

SessionOptions sessionOptions = new SessionOptions 
{ 
    Protocol = Protocol.Sftp, 
    HostName = "127.0.0.1", //hostname e.g. IP: 192.54.23.32, or mysftpsite.com 
    UserName = "xxxxxx", 
    Password = "yyyyyy", 
    PortNumber = zzzzz, //some number 
    SshHostKeyFingerprint = "ssh-rsa 1024 ::::04:85:3b:7a::::::::" 
}; 

using (Session session = new Session()) 
{ 
    session.Open(sessionOptions); //Attempts to connect to your sFtp site 
    //Get Ftp File 
    TransferOptions transferOptions = new TransferOptions(); 
    transferOptions.TransferMode = TransferMode.Binary; //The Transfer Mode - 
    // Automatic, Binary, or Ascii 
    transferOptions.FilePermissions = null; //Permissions applied to remote files; 
    //null for default permissions. Can set user, 
    //Group, or other Read/Write/Execute permissions. 
    transferOptions.PreserveTimestamp = false; //Set last write time of 
    //destination file to that of source file - basically change the timestamp 
    //to match destination and source files. 
    transferOptions.ResumeSupport.State = TransferResumeSupportState.Off; 

    TransferOperationResult transferResult; 
    //the parameter list is: local Path, Remote Path, Delete source file?, transfer Options 
    transferResult = session.PutFiles(@"C:\Adnan\a.txt", "/", false, transferOptions); 
    //Throw on any error 
    transferResult.Check(); 
    //Log information and break out if necessary 
}

我也遇到过这个例外.对我来说,它是在调用session.Open(...)时生成的.

但是,这是一个由WinSCP程序集生成和捕获的内部异常.我只注意到它,因为我已经将Visual Studio配置为在每次异常抛出时停止.如果我关闭此设置(或继续通过此设置和一些其他内部IOExceptions),SFTP连接将正确打开.
