Question

我有一些用Java编写的代码，我想将其转换为Xamarin（C＃）。我怎么能用C＃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 };

我不知道如何获得这个“boolean.class”和“＆lt;？＆gt;”也行不通。因为这会被称为

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

然后为每个包装器添加一些

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

Answer 1

在C＃中，它被称为Type而不是Class。事情的名称有点不同：

private static readonly Type[] mSetForegroundSignature = new Type[] { typeof(bool) };

Answer 2

与Class<T>等效的c＃为Type，boolean.class为typeof(bool) - 如果您想了解有关c＃反射的更多信息，请查看{{3 }}。这是翻译的代码：

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;
}

将boolean类添加到类数组中
