当我在我的 C# WebService 中抛出异常(SoapException，真正的异常作为内部异常)时，客户端收到异常并显示以下消息。我可以禁止所有 HTML 内容，只发送包含我想要的消息的异常吗？
这不是完整的消息，只是我不想删除的部分。
The request failed with the error message:

<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>

<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>

最佳答案
视情况而定，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都必须是 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; }
}
然后您像这样抛出自定义异常:
throw new FaultException<CustomFault>(new CustomFault("your custom message"));
