C# 示例中的 GKScore ReportScores 方法

Question

谁能告诉我如何使用 C# 编写 ReportScores 示例？我发现了很多关于它是如何用 objective-C 编写的示例，但不是用 C# 编写的，而且转换器很贵。我一直在使用旧的、现在已弃用的 GKScore ReportScore，并尝试迁移到新的 GKScore ReportScores。我在 ReportScores 方法的 Action 参数上苦苦挣扎。这是我的代码：

GKScore scoreReporter = new GKScore (category);
scoreReporter.Value = score;
GKScore[] allScores = new GKScore[] { scoreReporter };
scoreReporter.ReportScores(allScores, new Action<NSError> ((error) => {

在最后一行编译时出错：

Error CS0176: Static member `MonoTouch.GameKit.GKScore.ReportScores 
(MonoTouch.GameKit.GKScore[], System.Action 
<MonoTouch.Foundation.NSError>)' 
cannot be accessed with an instance reference, 
qualify it with a type name instead

如果我尝试先在这行之前：

Action<NSError> completionHandler = new Action<NSError> ();
scoreReporter.ReportScores(allScores, completionHandler

它在第一行出错：

method name expected

如果我尝试从 "new Action()" 中删除 'new'，它会出错：

Error CS0119: Expression denotes a type', where avariable', value' ormethod group' was expected

用C#怎么写！？

谢谢

没关系，我找到了答案。我最终这样做了：

GKScore scoreReporter = new GKScore (category);
scoreReporter.Value = score;
GKScore[] allScores = new GKScore[] { scoreReporter };
GKScore.ReportScores(allScores, (x) => {
    if(x == null){
        new UIAlertView ("Score reported", "Score Reported successfully", null, "OK", null).Show ();
    }
    else{
        new UIAlertView ("Score Reported Failed", "Score Reported Failed", null, "OK", null).Show ();
    }
    NSThread.SleepFor(1);
});
