如何使用反射

Question

想象一下，我有以下類調用與REF/OUT參數，方法是什麼？我知道的基本知識：

var type = typeof(Cow); 
var tryParse = type.GetMethod("TryParse"); 

var toParse = "..."; 

var result = (bool)tryParse.Invoke(null, /* what are the args? */);

你可以做這樣的事情：

static void Main(string[] args) 
{ 
    var method = typeof (Cow).GetMethod("TryParse"); 
    var cow = new Cow();   
    var inputParams = new object[] {"cow string", cow}; 
    method.Invoke(null, inputParams); 
} 

class Cow 
{ 
    public static bool TryParse(string s, out Cow cow) 
    { 
     cow = null; 
     Console.WriteLine("TryParse is called!"); 
     return false; 
    } 
}
