Question

当我在C＃WebService中抛出异常（SoapException，真正的异常作为内部异常）时，客户端会收到带有以下消息的异常。我可以压制所有HTML内容，只发送带有我想要的消息的异常。

这不是完整的信息，只是我不想摆脱的部分。

The request failed with the error message:
--
<html>
    <head>
        <title>Runtime Error</title>
        <style>
         body {font-family:"Verdana";font-weight:normal;font-size: .7em;color:black;} 
         p {font-family:"Verdana";font-weight:normal;color:black;margin-top: -5px}
         b {font-family:"Verdana";font-weight:bold;color:black;margin-top: -5px}
         H1 { font-family:"Verdana";font-weight:normal;font-size:18pt;color:red }

         pre {font-family:"Lucida Console";font-size: .9em}

         .error {margin-bottom: 10px;}
         .expandable { text-decoration:underline; font-weight:bold; color:navy; cursor:hand; }
        </style>
    </head>

    <body bgcolor="white">

            <h2> <i>Runtime Error</i> </h2></span>

            <font face="Arial, Helvetica, Geneva, SunSans-Regular, sans-serif ">

            <b> Description: </b>An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed.
            <br><br>

            <b>Details:</b> To enable the details of this specific error message to be viewable on the local server machine, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "RemoteOnly". To enable the details to be viewable on remote machines, please set "mode" to "Off".<br><br>

            <table width=100% bgcolor="#ffffcc">
               <tr>

               </tr>
            </table>

            <br>

            <b>Notes:</b> The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.<br><br>

               <tr>
                  <td>

<!-- Web.Config Configuration File -->

<configuration>
    <system.web>
        <customErrors mode="On" defaultRedirect="mycustompage.htm"/>
    </system.web>

                  </td>
               </tr>

这取决于，如果您使用的是WCF，则可以定义自定义异常。您希望客户端看到的所有异常必须是FaultException类型。

您的自定义异常如下所示：

    [DataContract]
    public class CustomFault
    {
       public CustomFault()
       {
       }

        public CustomFault(string message)
        {
            Message = message;
        }

        [DataMember]
        public string Message { get; private set; }
    }

然后抛出你的自定义异常：

throw new FaultException<CustomFault>(new CustomFault("your custom message"));

Answer 2

我认为你没有得到你所想的错误。看起来您的客户端无法访问您的服务并收到网页错误，将该html包装在soap异常中。由于您的Web服务不可访问，因此您无法在代码中执行任何操作。你能成功地在浏览器中加载你的WSDL吗？
