Question

我通过此代码调用我的Web服务，它运行良好。但是，它很慢。任何想法或其他方式更快地调用Web服务？

WebRequest request = WebRequest.Create("myurl");
request.Method = "POST";
request.Timeout = 5000;
request.Proxy = null;
string data = string.Format("fromidLinhVuc={0}", 0);
request.ContentLength = data.Length;
request.ContentType = "application/x-www-form-urlencoded";
var dataStream = new StreamWriter(request.GetRequestStream());
dataStream.Write(data);
dataStream.Close();
WebResponse response = request.GetResponse();
return response;

这可能是您的问题，也可能不是，但您需要using块：

WebRequest request = WebRequest.Create("myurl");
request.Method = "POST";
request.Timeout = 5000;
request.Proxy = null;
string data = string.Format("fromidLinhVuc={0}", 0);
request.ContentLength = data.Length;
request.ContentType = "application/x-www-form-urlencoded";
using (var dataStream = new StreamWriter(request.GetRequestStream()))
{
    dataStream.Write(data);
}
WebResponse response = request.GetResponse();
return response;

由于此代码返回实现WebResponse的{{1}}，因此调用者可以在IDisposable块中调用此代码，以确保using被称为。

通过这种或那种方式调用它，无法更快地建立远程Web服务。在任何情况下，您都必须等待响应，这是您无法控制的。所以没办法。

您可以做的事情是，您正在异步调用Web服务，以便在等待服务响应时继续。虽然不完全使网络服务更快，但这可能非常有益，取决于您的具体情况，实际上给人的印象是事情变得更快：

public async GetMyResponseAsync()
{
    WebRequest request = WebRequest.Create("myurl");
    request.Method = "POST";
    request.Timeout = 5000;
    request.Proxy = null;
    string data = string.Format("fromidLinhVuc={0}", 0);
    request.ContentLength = data.Length;
    request.ContentType = "application/x-www-form-urlencoded";
    var dataStream = new StreamWriter(request.GetRequestStream());
    dataStream.Write(data);
    dataStream.Close();
    WebResponse response = await request.GetResponseAsync();

    return response;
}

然后在你的调用代码中你可能会做某事。像这样

...
// Do stuff
var response = GetMyResponseAsync();
// Do more stuff unrelated to 'response'
// Do stuff with 'response'
...

与response无关的部分将立即执行，而另一部分将等到response可用...

更快的方式来调用Http POST Url / Service
