嗨,我读到这篇文章你正在使用HttpClient错误,它正在破坏你的软件,文章建议这些2

1. 使您的HttpClient静态
2. 除非您明确要查找特定行为(例如导致服务失败),否则不要将HttpClient丢弃或包装在使用中

现在像我这样的c#上的新手就会跟着它,就像这篇文章上发布的代码是原始代码,他说会使应用程序失败

using System;
using System.Net.Http;
namespace ConsoleApplication
{
    public class Program
    {
        public static void Main(string[] args)
        {
            Console.WriteLine("Starting connections");
            for(int i = 0; i<10; i++)
            {
                using(var client = new HttpClient())
                {
                    var result = client.GetAsync("http://aspnetmonsters.com").Result;
                    Console.WriteLine(result.StatusCode);
                }
            }
            Console.WriteLine("Connections done");
        }
    }
}

并修复它,他给了这个代码:

using System;
using System.Net.Http;
namespace ConsoleApplication
{
    public class Program
    {
        private static HttpClient Client = new HttpClient();
        public static void Main(string[] args)
        {
            Console.WriteLine("Starting connections");
            for(int i = …

嗨伙计们,我在安装vs 2013时遇到问题,下面的图片显示错误

我在Google上研究了很多,我发现在Windows 8.1上.net框架4.5.1已经是操作系统的一部分,当时vs 2013试图安装.net framework 4.5.1然后错误显示.
