当 ForEach 在数组中有多个项目时，为什么我在 Parallel.ForEach c# 中得到 net::ERR_CONNECTION_RESET？

如何解决当 ForEach 在数组中有多个项目时，为什么我在 Parallel.ForEach c# 中得到 net::ERR_CONNECTION_RESET？

所以我有一个用 C# 用 ASP.NET 编码的网站，单击按钮后，会发生以下情况。它执行一堆 RestRequest 并执行一些 API 调用。请参考以下示例：

 public static void Process(string[] aryIDs)
 {
    Parallel.ForEach(aryIDs,(PID) =>
    {
        bool status = ProcessList(PID);
    });
 }

 public static void ProcessList(string PID)
 {
    Method1(PID);
 }

public static bool Method1(string PID)
{
     ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12 | SecurityProtocolType.Ssl3;
     ServicePointManager.Expect100Continue = false;

     var client = new RestClient(URL);
     client.Timeout = -1;
     var request = new RestRequest(Method.POST);
     request.AddHeader("Connection","keep-alive");
     request.AddHeader("sec-ch-ua-mobile","?0");
     client.UserAgent = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML,like Gecko) Chrome/90.0.4430.93 Safari/537.36";
     request.AddHeader("Content-Type","application/json");
     request.AddHeader("Accept","application/json,text/javascript,*/*; q=0.01");
     request.AddHeader("X-Requested-With","XMLHttpRequest");
     request.AddHeader("sec-ch-ua","\" Not A;Brand\";v=\"99\",\"Chromium\";v=\"90\",\"Google Chrome\";v=\"90\"");
     request.AddHeader("Origin","https://somewhere.com");
     request.AddHeader("sec-fetch-site","same-origin");
     request.AddHeader("sec-fetch-mode","cors");
     request.AddHeader("Sec-Fetch-Dest","empty");
     request.AddHeader("Referer","https://somewhere.com/index.html");
     request.AddHeader("Accept-Language","en-US,en;q=0.9");

     IRestResponse response = client.Execute(request);
}

如果字符串数组中只有一个字符串，我的代码就可以正常工作，我猜这是因为 ProcessList 方法只被调用了一次。但是，如果字符串数组中有更多值，则会出现 net::ERR_CONNECTION_RESET 错误。我需要为与字符串数组中的元素一样多的元素同时运行 ProcessList 方法。

谁能告诉我发生了什么，我该怎么做才能达到预期的结果？
