無法在DLL“advapi32.dll”模擬異常中找到名為“LogonUser”的入口點

Question

在瀏覽一些遺留模擬邏輯時，我遇到以下異常：

無法在DLL“advapi32.dll”中找到名為“LogonUser”的入口點

我知道錯誤意味着我的應用程序無法在advapi32.dll中找到LogonUser方法。

代碼看起來像這樣：

[DllImport("advapi32.dll", CharSet = CharSet.Auto, SetLastError = true, ExactSpelling = true)]
private static extern bool LogonUser(String lpszUsername, String lpszDomain, String     lpszPassword, int dwLogonType, int dwLogonProvider, ref IntPtr phToken);



if(LogonUser(_username, _domainname, _password, LOGON32_LOGON_INTERACTIVE, LOGON32_PROVIDER_DEFAULT, ref _tokenHandle))
{
//do stuff...
}

有沒有人有類似的錯誤 - 有關如何解決它或為什么會發生的任何建議？ 除了使用advapi32.dll（它的.net 3.5解決方案，但有很多遺留類）之外，還有更好的方法嗎？

Answer 1

也許它與“ExactSpelling = true”有關

這似乎有效：

public enum LogonType : int
{
    Interactive = 2,
    Network = 3,
    Batch = 4,
    Service = 5,
    Unlock = 7,
    NetworkCleartText = 8,
    NewCredentials = 9,
}

public enum LogonProvider : int
{  
    Default = 0,
}

public class Impersonation : IDisposable
{
    #region Dll Imports

    [DllImport("kernel32.dll")]
    private static extern Boolean CloseHandle(IntPtr hObject);

    [DllImport("advapi32.dll", CharSet = CharSet.Auto, SetLastError = true)]
    private static extern bool LogonUser(string username, string domain,

                                          LogonProvider logonProvider,
                                          out IntPtr userToken);

    [DllImport("advapi32.dll", CharSet = CharSet.Auto, SetLastError = true)]

        ref IntPtr duplication);

          [DllImport("advapi32.dll", SetLastError = true)]

您是否嘗試過使用pinvoke.net上提供的LogonUser簽名版本？
