 7             string pwd = "123";
 8             string filePath = @"C:\Users\kevin\Desktop\1.jpg";
 9             string ftpIP = "ftp://192.168.100.104/";
10             
11             bool result= UploadFile(filePath, ftpIP, username, pwd);
12             if (result)
13                 Console.WriteLine("成功");
14             else
15                 Console.WriteLine("失败");
16             Console.ReadKey();
