你知道为什么发送http请求的ASP.NET C#代码不起作用吗？

代码如下，当我点击页面时：

它只是挂在加载杆上，永远缓慢地移动，直到我停下来，我忘记做什么了吗？我不知道哪一行代码是用来“提交”请求的

        HttpWebRequest objRequest = (HttpWebRequest)WebRequest.Create("https://[company name].updatelog.com/projects/" + project_id + "/time_entries.xml");

        string encodedData = Convert.ToBase64String(encData_byte);

        objRequest.Headers.Add("Authorization", "Basic " + encodedData);

我认为XmlWriter不会自动关闭GetRequestStream（）返回的流。加：

在创建XmlWriter之前，看看这是否有帮助。

作为旁注，您应该能够替换以下内容：

string creds = "username:password";
byte[] encData_byte = new byte[creds.Length];
encData_byte = System.Text.Encoding.UTF8.GetBytes(creds);
string encodedData = Convert.ToBase64String(encData_byte);

objRequest.Headers.Add("Authorization", "Basic " + encodedData);

是的，在你写完信后要冲水。是的，但是如果你不关闭它，冲水对你没有多大帮助。是的，在你写完信后要冲水。是的，但是如果你不关闭它，冲水对你没有多大帮助。

objRequest.Credentials = new NetworkCredential("username", "password");
