创建PrincipalContext时代码崩溃

Question

每当我调用这个方法时，我都会崩溃。

    public bool findSAMAccountByName(string environmentUserName)
    {
        try
        {
            const string Domain = "someserver";
            // set up domain context
            PrincipalContext ctx = new PrincipalContext(ContextType.Domain, Domain);

            // find a user
            UserPrincipal user = UserPrincipal.FindByIdentity(ctx, environmentUserName);

            if (user != null)
            {
                // do something here....     
                string samAccountName = user.SamAccountName;
                return true;
            }
            return false;
        }

        catch (Exception e)
        {
            e.ToString();
        }
        return false;
    }

内心的例外说

{“试图读取或写入受保护的内存。这通常表示其他内存已损坏”}

StackTrace是

 at System.DirectoryServices.Interop.UnsafeNativeMethods.IAds.GetEx(String bstrName, Object& value)
   at System.DirectoryServices.PropertyValueCollection.PopulateList()
   at System.DirectoryServices.PropertyValueCollection..ctor(DirectoryEntry entry, String propertyName)
   at System.DirectoryServices.PropertyCollection.get_Item(String propertyName)

   at ActiveRecord.MainWindow.findSAMAccountByName(String environmentUserName) in MainWindow.xaml.cs:line 60
   at ActiveRecord.MainWindow..ctor() in MainWindow.xaml.cs:line 39

我对这个方法的调用导致了崩溃。

                if (findSAMAccountByName(Environment.UserName))
                {
                    Console.WriteLine("Username found");
                }

如果我删除/注释代码，它将编译并运行良好。

更新:遵循DJ KRAZE的建议

const string Domain = "someserver";

在将PrincipalContext更改为接受2种增益之后，新的StackTrace是

      at System.Windows.Markup.WpfXamlLoader.Load(XamlReader xamlReader, IXamlObjectWriterFactory writerFactory, Boolean skipJournaledProperties, Object rootObject, XamlObjectWriterSettings settings, Uri baseUri)

像这样的可可粉应该能用。

const string Domain = "SomeServer.Foo.Bar.com";
const string Username = "someUserSamAccountName";

PrincipalContext principalContext = new PrincipalContext(ContextType.Domain, Domain);
UserPrincipal userPrincipal = UserPrincipal.FindByIdentity(principalContext,  Username);

用值替换，如果找到或没有找到用户，这个值应该会返回。我每天都和AD一起工作，只是用我的帐号进行测试，希望这能帮助你改变你的方法来传递字符串samAccount，字符串DomanName；

可以遵循的硬编码示例

const string Domain = "SLO1.Foo.Bar.biz:389";
const string Container = @"DC=Foo,DC=Bar,DC=biz";
const string Username = @"cocoadev";//replace with actual samAccountName
PrincipalContext principalContext = new PrincipalContext(ContextType.Domain, Domain, Container);
UserPrincipal userPrincipal = UserPrincipal.FindByIdentity(principalContext,  username);
