推荐答案

有没有内置的方式，但你可以简单地使用的方法来获得的反响流，并将其保存到一个文件中。

There's no builtin way, but you can simply use the GetResponseStream method to get the responce stream and save it to a file.

示例：

WebRequest myRequest = WebRequest.Create("http://www.example.com");
using (WebResponse myResponse = myRequest.GetResponse())
using (StreamReader reader = new StreamReader(myResponse.GetResponseStream()))
{
    // use whatever method you want to save the data to the file...
    File.AppendAllText(filePath, myResponse.Headers.ToString());
    File.AppendAllText(filePath, reader.ReadToEnd());
}

然而，你可以把它包装成一个扩展方法

Nonetheless, you can wrap it into an extension method

WebRequest myRequest = WebRequest.Create("http://www.example.com");
using (WebResponse myResponse = myRequest.GetResponse())
{
    myResponse.SaveAs(...)
}

...

public static class WebResponseExtensions
{
    public static void SaveAs(this WebResponse response, string filePath)
    {
        using (StreamReader reader = new StreamReader(response.GetResponseStream()))
        {
            File.AppendAllText(filePath, myResponse.Headers.ToString());
            File.AppendAllText(filePath, reader.ReadToEnd());
        }
    }
}
