1、在服务器设置一个共享文件夹,在这里我的服务器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
{
//ListBox1.Items.Add("未能连接!");
}
Console.ReadKey();
} public static bool connectState(string path)
{
return connectState(path, "", "");
}
/// <summary>
/// 连接远程共享文件夹
/// </summary>
/// <param name="path">远程共享文件夹的路径</param>
/// <param name="userName">用户名</param>
/// <param name="passWord">密码</param>
/// <returns></returns>
public static bool connectState(string path, string userName, string passWord)
{
bool Flag = false;
Process proc = new Process();
try
{
proc.StartInfo.FileName = "cmd.exe";
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.RedirectStandardInput = true;
proc.StartInfo.RedirectStandardOutput = true;
proc.StartInfo.RedirectStandardError = true;
proc.StartInfo.CreateNoWindow = true;
proc.Start();
string dosLine = "net use " + path + " " + passWord + " /user:" + userName;
proc.StandardInput.WriteLine(dosLine);
proc.StandardInput.WriteLine("exit");
while (!proc.HasExited)
{
proc.WaitForExit(1000);
}
string errormsg = proc.StandardError.ReadToEnd();
proc.StandardError.Close();
if (string.IsNullOrEmpty(errormsg))
{
Flag = true;
}
else
{
throw new Exception(errormsg);
}
}
catch (Exception ex)
{
throw ex;
}
finally
{
proc.Close();
proc.Dispose();
}
return Flag;
} /// <summary>
/// 向远程文件夹保存本地内容,或者从远程文件夹下载文件到本地
/// </summary>
/// <param name="src">要保存的文件的路径,如果保存文件到共享文件夹,这个路径就是本地文件路径如:@"D:\1.avi"</param>
/// <param name="dst">保存文件的路径,不含名称及扩展名</param>
/// <param name="fileName">保存文件的名称以及扩展名</param>
public static void Transport(string src, string dst,string fileName)
{ FileStream inFileStream = new FileStream(src, FileMode.Open);
if (!Directory.Exists(dst))
{
Directory.CreateDirectory(dst);
}
dst = dst + fileName;
FileStream outFileStream = new FileStream(dst, FileMode.OpenOrCreate); byte[] buf = new byte[inFileStream.Length]; int byteCount; while ((byteCount = inFileStream.Read(buf, 0, buf.Length)) > 0)
{ outFileStream.Write(buf, 0, byteCount); } inFileStream.Flush(); inFileStream.Close(); outFileStream.Flush(); outFileStream.Close(); }
}

按以上步骤,即可实现读写网络共享文件。
