C#如何去連接網絡共享目錄

[david0620]

在C#的（Winfrom或WEB）中如何去連接網絡上共享的目錄呢？

我在5楼贴的
[DllImport("mpr.dll")]
public static extern int WNetAddConnection2A(NETRESOURCE[] lpNetResource, string lpPassword, string lpUserName, int dwFlags);
调用时需要传入的是一个数组类型，你把传入类型给改了。
我本地又试了一下可以映射上的。

NETRESOURCE[] share_driver = new NETRESOURCE[1];
share_driver[0].dwType = RESOURCE_TYPE.RESOURCETYPE_DISK;
share_driver[0].lpLocalName = localPath;
share_driver[0].lpRemoteName = remotePath;

int ret = WNetAddConnection2A( share_driver, password, username, 1);

怎麼我用你的代碼還是不行啊？
你看看我的代碼看看哪裡有問題？
指點一下..

用你的代碼報錯:
[DllImport("mpr.dll")]
public static extern int WNetAddConnection2A( NETRESOURCE[] lpNetResource, string lpPassword, string lpUserName, int dwFlags);

[DllImport("mpr.dll")]
public static extern int WNetCancelConnection2A(string sharename, int dwFlags, int fForce);
NETRESOURCE[] share_driver = new NETRESOURCE[1];
share_driver[0].dwType = RESOURCE_TYPE.RESOURCETYPE_DISK;
share_driver[0].lpLocalName = localPath;
share_driver[0].lpRemoteName = remotePath;

Disconnect(localPath);
int ret = WNetAddConnection2A(@"serverip\temp", "pwd", "user", 1);

return ret;

[david0620]

報說沒有using NETRESOURCE

[basaka1982]

做个记号

将网络路径映射为本地的一个虚拟盘
然后就按操作本机文件一样操作这个文件就可以了

[jackljane]

网络上共享的目录如果权限比较低。在winform是里可以直接当作本地盘去操作的。如果有设有账号密码。则在代码里运行 cmd 执行net use 命令。把用户名密码作为参数打通路径之后再操作。
b/s里无法访问共享。因为结构不一样。客户在ie访问的时候根本就没有这个环境。你只能把服务器的局域网环境里的文件取过来放在iis目录下。或用网址访问

[david0620]

我在C#下實現，有代碼沒

[flyjimi]

使用win32 api

 [DllImport("mpr.dll")]
        public static extern int WNetAddConnection2A(NETRESOURCE[] lpNetResource, string lpPassword, string lpUserName, int dwFlags);

        [DllImport("mpr.dll")]
        public static extern int WNetCancelConnection2A(string sharename, int dwFlags, int fForce);
public static int Connect(string remotePath, string localPath, string username, string password)
        {
                NETRESOURCE[] share_driver = new NETRESOURCE[1];
                share_driver[0].dwType = RESOURCE_TYPE.RESOURCETYPE_DISK;
                share_driver[0].lpLocalName = localPath;
                share_driver[0].lpRemoteName = remotePath;

                Disconnect(localPath);
                int ret = WNetAddConnection2A(share_driver, password, username, 1);

                return ret;
        }

        public static void Disconnect(string localpath)
        {
            WNetCancelConnection2A(localpath, 1, 1);
        }

[kugou123]

C# 里面调用cmd去执行 net use ****的命令建立IPC连接。
然后可以映射成为一个本地盘符。这样就可以像操作本地盘一样去操作远程映射目录了。

private void InitializeComponent()

this.Load += new System.EventHandler(this.Page_Load);

}
#endregion

private void Button1_Click(object sender, System.EventArgs e)
{
NETRESOURCE myNetResource = new NETRESOURCE();
myNetResource.dwScope = 2; //2:RESOURCE_GLOBALNET
myNetResource.dwType = 1 ; //1:RESOURCETYPE_ANY
myNetResource.dwDisplayType = 3; //3:RESOURCEDISPLAYTYPE_GENERIC
myNetResource.dwUsage = 1; //1: RESOURCEUSAGE_CONNECTABLE
myNetResource.LocalName = "Y:";
myNetResource.RemoteName = @"\\ftp\temp\";
myNetResource.Provider = null;

uint nret = WNetAddConnection2( myNetResource, "user", "pwd", 0);
if(nret==0)
{
Response.Write("0");
}

}


為什麼我這樣還是不能將Y:映射出來啊

使用 NET USE 来保存用户和密码 .NET下就可以直接访问了

net use 不是我想要的

有誰看一下我的代碼，是哪裡有問題啊？

你這個還是用net use，我知道調用Process是可以實現批處理的功能啦，但是我不想用這個
