如何從不同的域「System.Runtime.InteropServices.COMException」用戶詳細信息

Question

我想從不同的域用戶的細節，但它拋出以下錯誤：

An exception of type 'System.Runtime.InteropServices.COMException' occurred in System.DirectoryServices.dll but was not handled in user code

守則如下圖所示：

// Getting domain 
var context = new DirectoryContext(DirectoryContextType.Domain, "alpha"); 
Domain domain = Domain.GetDomain(context); 

using (DirectorySearcher searcher = new DirectorySearcher()) 
{ 
    var de = new DirectoryEntry(domain.Name); 
    searcher.SearchRoot = de; 
    searcher.SearchScope = SearchScope.Subtree; 
    searcher.PropertiesToLoad.Add("sAMAccountName"); 
    searcher.Filter = string.Format("(&(objectClass=user)(sAMAccountName={0}))", "myusername"); 

    // *** ERROR HERE ***   
    var results = searcher.FindAll(); 
} 

我已經嘗試運行Visual Studio作爲域管理員，但沒有運氣。

在此先感謝。

以下代碼僅在使用System.DirectoryServices.ActiveDirectory添加名稱空間並添加引用時才起作用。

// Get user name 
string userName = User.Identity.Name; 
var domainName = username.Split('\\')[0]; 

// Getting domain 
var directoryContext = new DirectoryContext(DirectoryContextType.Domain, domainName); 
Domain domain = Domain.GetDomain(directoryContext); 

using (PrincipalContext principalContext = new PrincipalContext(ContextType.Domain, domain.Name)) 
{ 
    using (UserPrincipal user = UserPrincipal.FindByIdentity(principalContext, userName)) 
    { 
     if (user != null) 
     { 
      // Get details here 
      var name = user.GivenName; 
     } 
    } 
}
