Post 将超时 C# 控制台应用程序但不是 aspx 页面

Question

我有两个基本相同的应用程序，它们从文本文件（同一个）中读取行，然后将它们发布到 URL。当我在 .aspx 页面中运行代码时，代码总是毫无问题地发布。当我在控制台应用程序中运行它时，它只会在文本文件的前两行成功发布，然后总是在前两行之后超时。这对我来说没有意义，因为我得到了前两行的成功响应，然后它总是在同一点失败，但是对于 aspx 页面，我得到所有行的响应（例如 10 行）。我希望它在控制台应用程序表单中，以便我可以使用 Windows 任务计划程序安排它定期运行。

我的代码有问题，还是与使用控制台应用程序有关？

ASPX 页面：

<%@ Page Language="C#" Debug="true" %>
<%@ Import Namespace="System.Net"%>
<%@ Import Namespace="System.IO"%>
<%@ Import Namespace="System.Net.Mail"%>
<%
    //FILE PATH WHICH DATA IS PULLED FROM FOR POST
    string fileName = @"C:\TestDir\Test.txt";

    //READ ALL LINES OF TEXT FILE INTO AN ARRAY
    string[] lines = System.IO.File.ReadAllLines(fileName);
    string url = "http://testurl.com/test";

    //READ TEXT FILE LINE BY LINE
    foreach (string line in lines)
    {
        HttpWebRequest req = HttpWebRequest.Create(url) as HttpWebRequest;
        HttpWebResponse wr = null;
        string user = "testuser";
        string pwd = "testpassword";
        string mydata = line;
        byte[] byteData = Encoding.UTF8.GetBytes(mydata);
        UTF8Encoding enc = new UTF8Encoding();
        req.Method = "POST";
        string auth = "Basic " + Convert.ToBase64String(System.Text.Encoding.Default.GetBytes(user + ":" + pwd));
        req.PreAuthenticate = true;
        req.ContentType = "application/x-www-form-urlencoded";
        req.ContentLength = byteData.Length;
        req.Accept = "application/json";
        req.AuthenticationLevel = System.Net.Security.AuthenticationLevel.MutualAuthRequested;
        req.Headers.Add("Authorization", auth);
        using (Stream ds = req.GetRequestStream())
        {
            ds.Write(byteData, 0, byteData.Length);
            ds.Close();
        } try
        {
            wr = (HttpWebResponse)req.GetResponse();
        }
        catch (
        WebException ex)
        {
            wr = (HttpWebResponse)ex.Response;
        }
        Stream receiveStream = wr.GetResponseStream();
        StreamReader reader = new StreamReader(receiveStream, Encoding.UTF8);
        string content = reader.ReadToEnd();
        Response.Write(content + "Success");
    }

我发现问题是由于没有关闭响应。我在循环底部添加了wr.Close()，它可以正常工作。有趣的是，aspx 页面不会超时，但 C# 控制台应用程序会超时。
