新建一个工程,引用 Renci.SshNet.dll ,SFTP操作类如下:

测试代码片段如下:
private void btn_Start_Click(object sender, EventArgs e) { //var test = new SFTPOperation("172.28.103.9", "22", "sftp02", "sftp02"); var test = new SFTPOperation("172.28.103.9", "22", "sftp01", "sftp01"); // 上传文件 test.Put("D:/Download/ResourceSharp/test.txt", "china/in/test.txt"); //// 获取文件列表 //var list = test.GetFileList("china/in", "zip"); //foreach (var name in list) //{ // // 获取文件 // test.Get("china/in/" , "D:/Download/ResourceSharp/" + name); // Console.WriteLine(name); //} //// 删除文件 //test.Delete("china/in/aaa.txt"); //// 移动文件 //test.Move("china/in/test.txt", "china/test.txt"); }
