C# 反射-从System.Type实例获取泛型参数
如果我有以下代码:C# 反射-从System.Type实例获取泛型参数,c#,.net,reflection,generic-type-argument,C#,.net,Reflection,Generic Type Argument,如果我有以下代码: MyType<int> anInstance = new MyType<int>(); Type type = anInstance.GetType(); MyType anInstance=new MyType(); Type Type=anInstance.GetType(); 如何通过查看类型变量来找出实例化“anInstance”的类型参数?可能吗?使用。例如: using System; using System.Collections.
MyType<int> anInstance = new MyType<int>();
Type type = anInstance.GetType();
MyType anInstance=new MyType();
Type Type=anInstance.GetType();
如何通过查看类型变量来找出实例化“anInstance”的类型参数?可能吗?使用。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);
}
}
}
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> { }
}
使用Type.GetGenericArguments()。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);
}
}
}
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> { }
}
使用系统;
运用系统反思;
命名空间控制台应用程序1{
班级计划{
静态void Main(字符串[]参数){
MyType anInstance=新的MyType();
Type Type=anInstance.GetType();
foreach(Type.GetGenericArguments()中的类型t)
Console.WriteLine(t.Name);
Console.ReadLine();
}
}
公共类MyType{}
}
输出:
Int32
