Question

问题描述：最近，我想用C＃请求一个SilverLight页面的数据，我用Fiddle2.0分析了SVC链接地址（服务器是由政府开发的，所以我没有得到服务器数据的格式），fiddle2.0包RAW显示如下：

在我的程序中，我关心一个C＃项目，并使用svcutils生成数据契约类，通过WCF链接地址，我可以获取数据，但WSDL显示一个函数返回Base64Binary数据，如下所示：

在客户端上，我可以获得这个Base64Binary数据，但是当我解码这段代码时，它会显示混乱的代码。我使用下面的功能： Convert.tobase64string(bytes)

我想得到帮助，最好给我C＃代码。

=============================================== ================================== 嗨，evgenyl，谢谢你的回复！以下是详细代码：

我用工具SVCUTIL.exe生成了generatedProxy.cs，代码如下：

 [System.Diagnostics.DebuggerStepThroughAttribute()]
    [System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "3.0.0.0")]
    public partial class EnvAQIServeiceClient :       
    System.ServiceModel.ClientBase<IEnvAQIServeice>, IEnvAQIServeice
    {
      ...
      public byte[] GetAllAQIPublish0320()
      {
        return base.Channel.GetAllAQIPublish0320();
      }
      ...
    }

在我的C＃程序中，我只有三个陈述：

EnvAQIServeiceClient myclient = new EnvAQIServeiceClient(); 
byte[] Bytes = myclient.GetDataAndIAQI0320("北京", "");
string str=Convert.tobase64string(Bytes)

字符串str值如下：

WSDL文件部分描述此响应如下（type =“xs：base64binary”）：

<xs:element name="GetDataAndIAQI0320">

<xs:sequence>
<xs:element minOccurs="0" name="cityName" nillable="true" type="xs:string"/>

</xs:sequence>
</xs:complexType>
</xs:element>

在互联网上很多人都说：Silverlight页面返回的值是由GZIP压缩，deflate，所以，我发现GZipStream函数解码了值，但代码显示错误：幻数不正确，解码函数如下：

MemoryStream ms = new MemoryStream(Bytes, 0, Bytes.Length);
GZipStream gzip = new GZipStream(ms, CompressionMode.Decompress);
string pts = "";
using (StreamReader reader = new StreamReader(gzip))
{
  pts = reader.ReadToEnd();
}

所以，我很困惑。我很乐意帮忙！

Answer 1

你确定它的base64？当我尝试解码它时（在记事本++中） - 我没有收到有效的字符串。

请发布您的代码

在客户端如何解码Base64binary
