ASP.. NET MVC:我在哪里可以得到示例MVC项目

尝试MVC示例页面，他们有认证的例子，应该是你所追求的。

或者有经典的书呆子晚餐

对于动作过滤器本身并没有太多的要求，具体的身份验证将取决于您的需求，您没有详细说明:

/// <summary>
/// Custom authorization attribute for use on controllers and actions. 
/// Throws an exception if the user is not authorized.
/// </summary>
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method)]
public sealed class ActionPermissionAttribute : AuthorizeAttribute
{
    public override void OnAuthorization(AuthorizationContext filterContext)
    {
        // Override OnAuthorization, not AuthorizeCore as AuthorizeCore will force user login prompt rather than inform the user of the issue.
        var controller = filterContext.ActionDescriptor.ControllerDescriptor.ControllerName;
        var action = filterContext.ActionDescriptor.ActionName;
        var user = HttpContext.Current.Request.LogonUserIdentity;
        // Check user can use the app or the specific controller/action
        var authorised = ...
        if (!authorised)
            throw new UnauthorizedAccessException("You are not authorised to perform this action.");
        base.OnAuthorization(filterContext);
    }
}
