ftp上传单一文件示例

废话不多说，直接上代码

 1  class Program
    {
        static void Main(string[] args)
        {
           
            string username = "abc";
            string pwd = "123";
            string filePath = @"C:UserskevinDesktop1.jpg";
            string ftpIP = "ftp://192.168.100.104/";
            
            bool result= UploadFile(filePath, ftpIP, username, pwd);
            if (result)
                Console.WriteLine("成功");
            else
                Console.WriteLine("失败");
            Console.ReadKey();
        }
