The TCP connection pool reuse

[yilezhu]

When I test restsharp for requests, I find that there are many TCP connections established. Can these TCP connections be reused? If I have too many requests, the established TCP connection will occupy all my local ports and eventually cause my program to crash！
The test code :

 var client = new RestClient("https://www.cnblogs.com/yilezhu/p/12830123.html");
            var request = new RestRequest();
            var response = client.Get(request);
            Console.WriteLine("100个请求测试开始~~~~" + DateTime.Now);
            Stopwatch stopwatch = Stopwatch.StartNew();
            await Task.WhenAll(Enumerable.Range(0, 100)
               .Select(_ => Task.Run(() =>
             {
                 var response = client.Get(request);
             }))).ConfigureAwait(false);
            stopwatch.Stop();

            Console.WriteLine("100个请求测试结束~~~~" + DateTime.Now);
            Console.WriteLine("总共用时" + stopwatch.ElapsedMilliseconds / 1000 / 60 + "分钟");

The TCP connections I see through tcpview are as follows：

Maybe you could try HttpClient instead of RestSharp.
