java - 将 boolean 类添加到类数组中

Question

我有一些用 Java 编写的代码，我想将其转换为 Xamarin (C#)。我怎样才能用 C# 编写这个？

private static final Class<?>[] mSetForegroundSignature = new Class[] { boolean.class };
private static final Class<?>[] mStartForegroundSignature = new Class[] { int.class, Notification.class };
private static final Class<?>[] mStopForegroundSignature = new Class[] { boolean.class };

我不知道如何获取这个“boolean.class”，并且“ ”也不起作用。因为这样就会被调用

Method mStartForeground = getClass().getMethod("startForeground", mStartForegroundSignature);

然后为每个喜欢一些包装

if (mStartForeground != null) {
        mStartForegroundArgs[0] = Integer.valueOf(id);
        mStartForegroundArgs[1] = notification;
        invokeMethod(mStartForeground, mStartForegroundArgs);
        return;
    }

相当于 Class<T> 的 C#是 Type ，以及 boolean.class这是typeof(bool) - 如果您想了解有关 C# 反射的更多信息，请查看 this tutorial 。这是翻译后的代码:

签名:

private static readonly Type[] mSetForegroundSignature = new Type[] { typeof(bool) };
private static readonly Type[] mStartForegroundSignature = new Type[] { typeof(int), typeof(Notification) };
private static readonly Type[] mStopForegroundSignature = new Type[] { typeof(bool) };

获取方法对象:

System.Reflection.MethodInfo mStartForeground = new this.GetType().GetMethod("startForeground", mStartForegroundSignature);

调用方法:

if(mStartForeground != null) {
    mStartForegroundArgs[0] = Convert.ToInt32(id);
    mStartForegroundArgs[1] = notification;
    //invoke via reflection (it may be different to invokeMethod?)
    mStartForeground.Invoke(instance, mStartForegroundArgs);
    return;
}
