C#中的event直接调用和Invoke的区别，是否性能有差异

class Student:INotifyPropertyChanged
    {
        public event PropertyChangedEventHandler PropertyChanged;
        private string name;

        public string Name
        {
            get { return name; }
            set
            {
                name = value;
                //激发事件
                if ( this.PropertyChanged != null )
                {
                    //this.PropertyChanged( this , new PropertyChangedEventArgs( "Name" ) );//这样跟下面有什么不同？
                    this.PropertyChanged.Invoke( this , new PropertyChangedEventArgs( "Name" ) );
                }
            }
        }
    }

两条语句都可以实现一样的功能，只是写法不同而已吗？Which is faster; using event.Invoke(args), or just calling event(args). What's the difference? Is one faster or slower than the other; or is it just a matter of preference?（哪种性能会更好？）

答：完全一样，编译期会将 event(args)转成event.Invoke(args)。两者都转成相同的IL代码。对于DynamicInvoke，会使用反射，从而性能较差
