如果我有以下代码:
If I have the following code:
MyType<int> anInstance = new MyType<int>();
Type type = anInstance.GetType();
通过查看类型变量,我如何找出“anInstance”实例化时使用的哪些类型参数?这可能吗?

使用 Type.GetGenericArguments 方法。例如:
using System;
using System.Collections.Generic;
public class Test
{
static void Main()
{
var dict = new Dictionary<string, int>();
Type type = dict.GetType();
Console.WriteLine("Type arguments:");
foreach (Type arg in type.GetGenericArguments())
{
Console.WriteLine(" {0}", arg);
}
}
}
输出:
Type arguments:
System.String
System.Int32
using System;
using System.Reflection;
namespace ConsoleApplication1 {
class Program {
static void Main(string[] args) {
MyType<int> anInstance = new MyType<int>();
Type type = anInstance.GetType();
foreach (Type t in type.GetGenericArguments())
Console.WriteLine(t.Name);
Console.ReadLine();
}
}
public class MyType<T> { }
}
