本文详细解析了C#中通过typeof方法创建类型别名的语法和实现过程，通过实例展示了如何正确地使用类型别名，并揭示了常见错误及解决策略。

I have seen from some book where this kind of code has been given.

Type[] types = typeof(TypeA, TypeB);

whether it is some new feature that has y et to be supported now, or is it somehting that is typo from the original books...
Let's give a try, and below is the test result.

    class TypeA
    { }

    class TypeB
    {
    }

    class Program
    {
        static void Main(string[] args)
        {
            Type[] types = typeof(TypeA, TypeB);
            if (types.Length > 0)
            {
                Console.WriteLine("syntax type(ypeA, TypeB) is OK");
            }
            else
            {
                Console.WriteLine("syntax type(TypeA, TypeB) is not OK");
            }
        }
    }

while, the code stop to compile in the first place. so the myth-buster, typeof can accept more than one type as arguments - proven false.
