我想暴露WebClient.DownloadDataInternal方法,如下所示:

[ComVisible(true)]
public class MyWebClient : WebClient
{
    private MethodInfo _DownloadDataInternal;

    public MyWebClient()
    {
        _DownloadDataInternal = typeof(WebClient).GetMethod("DownloadDataInternal", BindingFlags.NonPublic | BindingFlags.Instance);
    }

    public byte[] DownloadDataInternal(Uri address, out WebRequest request)
    {
        _DownloadDataInternal.Invoke(this, new object[] { address, out request });
    }

}

WebClient.DownloadDataInternal有一个out参数,我不知道如何调用它.救命!

当我将SchemaExport与SQL Server 2005一起使用时,它会生成唯一的密钥名称,如:

UQ__Employees__03317E3D

如何生成如下名称:UQ__Employees__Name？即使在SQL Server中!

我写了一个如下控制器:

public class AccountController : Controller
{
    public ActionResult Login(/*---*/)
    {
        GenericIdentity identity = new GenericIdentity("userName");
        GenericPrincipal principal = new GenericPrincipal(identity, new string[] { "role1", "role2" });
        this.HttpContext.User = principal;
        /*---*/;
    }
}

登录后,我可以通过其他控制器中的User.Identity.Name获取用户名.但User.IsInRole("role1")始终返回false.

如何为User分配值,我不想使用Membership ...
