C# 从PowerShell调用WNetAddConnection2

我正试图从PowerShell脚本直接调用一些Win32 API。我成功地使用以下代码使WNetAddConnection工作：

$cp = New-Object Microsoft.CSharp.CSharpCodeProvider
$cpar = New-Object System.CodeDom.Compiler.CompilerParameters

$Code = @"
using System;
using System.Runtime.InteropServices;
namespace Win32Api
{
    public class Net
    {
        [DllImport("mpr.dll", EntryPoint = "WNetAddConnection")]
        public static extern uint Map(string lpRemoteName, string lpPassword, string lpLocalName);
        [DllImport("mpr.dll", EntryPoint = "WNetCancelConnection")]
      public static extern uint Delete(string lpName, byte fForce);     
    }
}
"@

$cp.CompileAssemblyFromSource($cpar, $code)
[Win32Api.Net]::Map("\\REMKOLAPTOP\C$", $null, "W:")

现在我想做同样的事情，尽管我找到了正确的方法，但我不确定如何声明它在PowerShell中的使用。所以我的问题是：什么是正确的“翻译”和调用API的示例将非常好

请注意，我不想使用以下非api方法：

$net = $(New-Object -Com WScript.Network)
$net.MapNetworkDrive("u:", "\\computer\share")

我能够在PowerShell 2.0上获得以下代码。请注意，我还使用了一个PSCX（）函数，该函数仅将Windows错误代码转换为消息。我还设置了一些选项，以交互提示输入用户名和密码。其中包含注释掉的脚本，显示了如何使用PowerShell的Get-Credential cmdlet执行相同操作

顺便说一句，如果您通过变量向函数提供用户名/密码，请确保顺序正确，密码后跟用户名。那咬了我10分钟，直到我终于发现我点错了。啊！另一个小贴士是，要获得像这样的互操作帮助，请务必签出。不管怎样，希望这有帮助

我没有在PS1.0中得到任何错误，但是它还不能工作。脚本似乎无限期地等待。与我的代码相比，我错过了compileasemblyfromsource（$cpar，$code），因此我将尝试对其进行调整，然后看看它是否有效。现在将您的解决方案标记为helpfull。代码在PS2.0中工作，请注意：$res=[Win32Api.NativeMethods]：:WNetAddConnection2（$netResource，$null，$null，$opts）在工作的地方不起作用：$res=[Win32Api.NativeMethods]：：WNetAddConnection2（$netResource，0，0，$opts）我很高兴能为您工作。我花了一点时间在那个愚蠢的签名上。我以为是用户名加密码。
