c# - System.EntryPointNotFoundException 和 DllImport ("kernel32.dll")

Question

为什么我在这段代码中有一个 EntryPointNotFoundException。 (来源 pinvoke.net)我的操作系统是 Windows XP SP3。

using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;

namespace System_Info
{
    class Program
    {
        [DllImport("kernel32.dll", SetLastError = false)]
        static extern bool GetProductInfo(
             int dwOSMajorVersion,
             int dwOSMinorVersion,
             int dwSpMajorVersion,
             int dwSpMinorVersion,
             out int pdwReturnedProductType);

        static void Main(string[] args)
        {

            int ProductNum;

            GetProductInfo(
             Environment.OSVersion.Version.Major,
             Environment.OSVersion.Version.Minor,
             0,
             0,
             out ProductNum);

            Console.WriteLine(Environment.OSVersion.Version.Build);
            Console.WriteLine(Environment.OSVersion.Version.Major);
            Console.WriteLine(Environment.OSVersion.Version.MajorRevision);
            Console.WriteLine(Environment.OSVersion.Version.Minor);
            Console.WriteLine(Environment.OSVersion.Version.MinorRevision);
            Console.WriteLine(Environment.OSVersion.Version.Revision);

            Console.WriteLine(ProductNum);

            Console.ReadKey();
        }
    }
}

问候，
