【问题标题】:How to open a folder with authentication in c#?如何在 C# 中打开具有身份验证的文件夹?

【问题描述】:

如何在c#中打开带有身份验证的文件夹? 我已经使用了 LogonUser,但它不起作用...

IntPtr token = IntPtr.Zero;
bool success = LogonUser("username", "domainname", "password",
    2, 0, ref token);
if (success)
{
    using (WindowsImpersonationContext person = new WindowsIdentity(token).Impersonate())
    {
        File.Copy(sourceFileName,destFileName);

        person.Undo();
        CloseHandle(token);
    }
}

Succes 为真,我在令牌中收到一个数字,它输入 if 并给出用户错误和密码。

一切正常,直到它到达 File.Copy 部分错误:我 仍然收到此错误“其他信息:登录失败:未知 用户名或密码错误。”

【问题讨论】:

  • 问:具体的错误是什么?问:它是否与源文件夹、源文件、目标文件夹、用户身份或“其他”有关?
  • 还要检查您传递给SoddingNetworkAuth的参数,它们必须是以下项目,按以下顺序;用户名、服务器名、密码。我的代码将其从该页面中删除webmisterradixlecti.blogspot.com/2012/09/… 在到达 File.Copy 部分之前一切正常 错误:我仍然收到此错误“其他信息:登录失败:未知用户名或密码错误。”
  • 寻求调试帮助的问题(“为什么这段代码不起作用?”)必须包括所需的行为、特定的问题或错误以及在问题本身中重现它所需的最短代码. - 来自What topics can I ask about here? 的第 1 点。请edit您的问题将错误从您的评论移到问题中。
  • 您是否尝试过 msft/docs 中的示例?它就像一个魅力:docs.microsoft.com/en-us/dotnet/api/…

我更改了代码,它对我来说是正确的,我把它留在这里以防有人需要它。

    public class NetworkShare
    {
        [DllImport("Mpr.dll")]
        private static extern int WNetUseConnection(
            IntPtr hwndOwner,

        [DllImport("Mpr.dll")]
        private static extern int WNetCancelConnection(
            string lpName,
            bool fForce
            );

        [StructLayout(LayoutKind.Sequential)]
        private class NETRESOURCE

            public string lpLocalName = "";
            public string lpRemoteName = "";
            public string lpComment = "";
            public string lpProvider = "";
        }

        const int RESOURCETYPE_DISK = 0x00000001;
        const int CONNECT_UPDATE_PROFILE = 0x00000001;


        public static void ConnectToShare(string uri, string username, string password, string idFile, HttpPostedFileBase file)
        {
            //Create netresource and point it at the share
            NETRESOURCE nr = new NETRESOURCE();
            nr.dwType = RESOURCETYPE_DISK;
            nr.lpRemoteName = uri;

            //Create the share
            int ret = WNetUseConnection(IntPtr.Zero, nr, password, username, 0, null, null, null);

            file.SaveAs(@"\\c:\Desktop\FolderName\" + idFile);

        }

        public static void DisconnectFromShare(string uri, bool force)
        {
            //remove the share
            int ret = WNetCancelConnection(uri, force);

        }



    }
}

然后从您的代码中调用它:

 ConnectToShare("dom", @"user", @"psw", file);
  DisconnectFromShare("dom", false);
