如果我有一个特定类型的数组，有没有办法分辨出该类型到底是什么?

If I have an array of a particular type is there a way to tell what exactly that type is?

 var arr = new []{ "string1", "string2" };
 var t = arr.GetType();
 t.IsArray //Evaluates to true

 //How do I determine it's an array of strings?
 t.ArrayType == typeof(string) //obviously doesn't work

推荐答案

Type.GetElementType - When overridden in a derived class, returns the Type of the object encompassed or referred to by the current array, pointer or reference type.

var arr = new []{ "string1", "string2" };
Type type = array.GetType().GetElementType();
