How do I use reflection to determine the nested type (element type) of an array?
提问by Paul Hollingsworth
I have an instance of System.Type, for which "IsArray" returns true.
我有一个 System.Type 实例,“IsArray”返回 true。
How can I determine the "nested type" of the array type?
如何确定数组类型的“嵌套类型”?
i.e.
IE
Type GetArrayType(Type t)
{
if(t.IsArray)
{
// What to put here?
}
throw new Exception("Type is not an array");
}
Assert.That(GetArrayType(typeof(string[])), Iz.EqualTo(typeof(string));
Assert.That(GetArrayType(typeof(Foo[])), Iz.EqualTo(typeof(Foo));
