我正在使用的 Web 服务返回了 Web 异常。从 Silverlight 应用程序调用服务。基本上我正在尝试将 eps 文件转换为 png 。在本地主机上一切正常，但是当我部署在 Web 服务器上时，我收到了这个错误。Silverlight 代码是——

  private void btnUploadImage_Click(object sender, RoutedEventArgs e)
        {

            //throw new NotImplementedException();
        }

错误在System.Net.Browser.BrowserHttpWebRequest。

请问这是什么问题？

这可能与这条线有关。

pcs.Endpoint.Address = new System.ServiceModel.EndpointAddress(virtualpath +

你错过了它的其余部分。很确定这是一个编译错误。

因此，要么这个错误被吃掉并且通用的错误正在弹出，要么你还有其他一些问题。
