SFTP SSH.NET DLL instead of SharpSSH
提问by billybob
I was seeking for a free DLL for .net to handle SFTP connections.
我正在为 .net 寻找一个免费的 DLL 来处理 SFTP 连接。
I found out this project SharpSSH, but it lacks of documentation.
我发现了这个项目SharpSSH，但它缺乏文档。
I spent a lot of time to figure how the dll works. I created a test project and I started to test different functions. Some functions are working such as deleting files.
我花了很多时间来弄清楚 dll 是如何工作的。我创建了一个测试项目并开始测试不同的功能。某些功能正在运行，例如删除文件。
I have a problem with putfile() function and getfile().
我对 putfile() 函数和 getfile() 有问题。
Here an example :
这里有一个例子：
Dim ssh As SFTPUtil
ssh = New SFTPUtil("MY SERVER", "MY USER", "MY PW")
ssh.GetFile("/home/sftptest/test111.xml", "C:\text.xml")
Note that the getfile() parameters are:
请注意，getfile() 参数是：
Public Sub GetFile(remotePath As String, localPath As String)
I step in the functions, but I didn't get the correct way to pass those parameters.
我介入了这些函数，但我没有得到传递这些参数的正确方法。
I dont really know if i should use slashes(/) or backslashes (). I know that Linux uses (/)
我真的不知道我应该使用斜杠（/）还是反斜杠（）。我知道 Linux 使用 (/)
I noticed for example that the "C:\" has been transformed to "C:\\".
例如，我注意到“C:\”已转换为“C:\\”。
Just to mention that the SFTP is on a linux machine.
顺便提一下，SFTP 在 linux 机器上。
thank you.
谢谢你。

Here's What I should have done (vb.net code) to establish the connection with THIS library (SSHnet), I did notuse SharpSHH:
这是我应该做的（vb.net代码）建立与连接这个库（SSHnet），我并没有使用SharpSHH：
Private Sub ButtonAction_Click(sender As Object, e As System.EventArgs) Handles ButtonAction.Click
Dim PasswordConnection = New PasswordAuthenticationMethod("test", "test")
Dim KeyboardInteractive = New KeyboardInteractiveAuthenticationMethod("test")
Dim ConnectionInfo = New ConnectionInfo("192.168.1.1", 22, "test", PasswordConnection, KeyboardInteractive)
AddHandler KeyboardInteractive.AuthenticationPrompt, _
Sub(_sender As Object, _e As Renci.SshNet.Common.AuthenticationPromptEventArgs)
For Each prompt In _e.Prompts
Debug.Print(prompt.Request)
If Not prompt.Request.IndexOf("Password:", StringComparison.InvariantCultureIgnoreCase) = -1 Then
prompt.Response = "test"
End If
Next
End Sub
sftp = New SftpClient(ConnectionInfo)
sftp.Connect()
sftp.disconnect()
End Sub

I have some problem understanding what exactly you want so here is an example code from the SSH.NET package. (NOT SharpSSH)
我在理解您到底想要什么时遇到了一些问题，所以这里是来自 SSH.NET 包的示例代码。（不是 SharpSSH）
string IP = "192.168.1.1", User = "Testuser", Pass = "123";
SftpClient sftp;
private void UploadFileSFTP()
{
sftp = new SftpClient(IP, User, Pass);
sftp.Connect();
Uploader();
Downloader();
sftp.Disconnect();
}
string FilePath="C:\folder\", Filename = "Filename.extention",
DeliveryPath = "/tmp/";
private void Uploader()
{
using (var file = File.OpenRead(FilePath + Filename))
{
sftp.UploadFile(file, DeliveryPath + Filename);
}
}
//there is possibly a simpler way to download but this is how i did it.
string FromPath = "/tmp/testfile.txt", StoragePath = "";
private void Downloader()
{
if (File.Exists(StoragePath))
File.Delete(StoragePath);
if (!Directory.GetDirectories(Path.GetTempPath()).Contains("WorkFiles"))
{
Directory.CreateDirectory(Path.GetTempPath() + "WorkFiles");
}
StoragePath = Path.GetTempPath() + "WorkFiles\testFile.txt";
Int64 iSize = sftp.ReadAllBytes(FromPath).Length;
Int64 iRunningByteTotal = 0;
using (Stream streamRemote = sftp.OpenRead(FromPath))
{
using (Stream streamLocal = new FileStream(StoragePath, FileMode.Create, FileAccess.Write, FileShare.None))
{
int iByteSize = 0;
byte[] byteBuffer = new byte[iSize];
while ((iByteSize = streamRemote.Read(byteBuffer, 0, byteBuffer.Length)) > 0)
{
streamLocal.Write(byteBuffer, 0, iByteSize);
iRunningByteTotal += iByteSize;
}
}
}
}

This library is full of bugs. I downloaded version at 11/2012 and I have big problem even with simple function like Disconnect. Application will freeze and you have to restart it.
这个库充满了错误。我在 11/2012 下载了版本，即使使用像断开连接这样的简单功能，我也遇到了大问题。应用程序将冻结，您必须重新启动它。
