我正在尝试使用以下app.config设置程序集绑定重定向:

<configuration>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="Microsoft.AnalysisServices"
                          PublicKeyToken="89845dcd8080cc91" />
        <bindingRedirect oldVersion="10.0.0.0"
                         newVersion="9.0.0.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
</configuration>

我在GAC中使用版本9.0.242.0的计算机上运行该程序,并使用指定的公钥令牌.CLR似乎甚至没有尝试重定向绑定以使用该版本.

这是我在fuslogvw.exe中得到的:

我需要在IIS中修改某些HttpRequests(SSAS连接字符串)的内容.基本上,我需要向请求中包含的SOAP添加一个元素.

到目前为止,我的方法是向HttpRequest添加一个Filter,并在过滤器的Read方法中执行更改.据我所知,Read永远不会被执行.

我对Request.Filter的理解是它从IIS处理请求时读取,因此IIS应该看到我修改过的Request.

我正在尝试使用HttpModule实际可行的是我的Filter方法是否正确？

如果是这样,什么会导致Read不被击中？

这是我的代码的简化版本:

public class CustomHttpModule : IHttpModule {
    private HttpApplication app;
    public string ModuleName {
        get { return "CustomHttpModule"; }
    }
    public void Init(HttpApplication context) {
        app = context;
        context.PreRequestHandlerExecute += new EventHandler(context_PreRequestHandlerExecute);
    }
    void context_PreRequestHandlerExecute(object sender, EventArgs e) {
        var request = app.Context.Request;
        request.Filter = new CustomHttpFilter(request.Filter);
    }
}

public class CustomHttpFilter : Stream {
    private Stream outputStream;
    public CustomHttpFilter(Stream outputFilter) {
        outputStream = outputFilter;
    }
    public override int Read(byte[] buffer, int offset, int count) …
