参考：http://codeblog.vurdalakov.net/2013/05/add-gzip-and-deflate-decompression-to-soap-web-service-client.html

需要翻墙才能看，我把代码部分摘录在下面：

 ...

// This source code was auto-generated by wsdl, Version=2.0.50727.3038.
public partial class MyWebServiceProxy : System.Web.Services.Protocols.SoapHttpClientProtocol {
...
}

...

public class MyWebServiceProxyGzip : MyWebServiceProxy
{
    protected override System.Net.WebRequest GetWebRequest(Uri uri)
    {
        WebRequest webRequest = base.GetWebRequest(uri);
        HttpWebRequest httpWebRequest = webRequest as HttpWebRequest;

        if (httpWebRequest != null)
        {
            httpWebRequest.AutomaticDecompression = DecompressionMethods.Deflate | DecompressionMethods.GZip;
        }

        return webRequest;
    }
}

...

    public void ReadUserInformation(String userName)
    {
        MyWebServiceProxyGzip myWebServiceProxyGzip = new MyWebServiceProxyGzip()
        {
            Url = "http://myservice.mydomain.com/WebService.aspx"
        };

        UserInformation userInformation = myWebServiceProxyGzip.GetUserInformation(userName);
    }
