如何使用System.Linq.Expressions应用程序接口模拟"typeof (T)“？

using System;
using System.Linq.Expressions;

public class Program
{
    public static void Main()
    {
        Type type = typeof(int); // 编译时获取类型

        // 使用System.Linq.Expressions来模拟"typeof(T)"
        Type dynamicType = GetDynamicType<int>();

        Console.WriteLine(type); // 输出：System.Int32
        Console.WriteLine(dynamicType); // 输出：System.Int32
    }

    public static Type GetDynamicType<T>()
    {
        Expression<Func<Type>> expression = () => typeof(T);
        UnaryExpression body = (UnaryExpression)expression.Body;
        ConstantExpression constant = (ConstantExpression)body.Operand;
        return (Type)constant.Value;
    }
}
