c# - 如何从不同域“System.Runtime.InteropServices.COMException”获取用户详细信息

Question

我正在尝试从不同的域获取用户详细信息，但它会引发以下错误：

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

代码如下：

// 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();
}

我已经尝试以域管理员身份运行 Visual Studio，但没有运气。

提前致谢。

以下代码仅在您使用 System.DirectoryServices.ActiveDirectory 添加名称空间并添加引用时才有效。

// 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;
        }
    }
}
