C#读写共享文件夹

该考试分以下步骤:

1、在服务器设置一个共享文件夹,在此地自己的服务器ip地址是10.200.8.73,共享文件夹名字是share,访问权限,用户名是administrator,密码是11111111。

2、新建一个控制台项目。

3、添加后台代码如下:

 class Program
    {
        static void Main(string[] args)
        {

            bool status = false;

            //连接共享文件夹
            status = connectState(@"\\10.200.8.73\share", "administrator", "11111111");
            if (status)
            {
                //共享文件夹的目录
                DirectoryInfo theFolder = new DirectoryInfo(@"\\10.200.8.73\share");
                //相对共享文件夹的路径
                string fielpath=@"\123\456\";
                //获取保存文件的路径
                string filename = theFolder.ToString() +fielpath ;
                //执行方法
                Transport(@"D:\1.jpg", filename, "1.jpg");

            }
            else
