Asp.net mvc 3 ServiceStack：如何在写入响应之前捕获错误

我使用ServiceStack开发了一个Rest服务。 我的模型包含DateTime属性，问题从它开始。如果客户端将日期值的格式设置为字符串，ServiceStack将引发异常“字符串未被识别为有效的DateTime”

堆栈跟踪：
[格式异常：字符串未被识别为有效的日期时间。]
System.DateTime.Parse（字符串s，IFormatProvider提供程序，DateTimeStyles样式）+6364458
C:\src\ServiceStack.Text\src\ServiceStack.Text\Common.DeserializeBuiltin`1.b\u\b（字符串值）中的ServiceStack.Text.Common.DeserializeBuiltin`1.b（字符串值）：58
ServiceStack.ServiceModel.Serialization.StringMapTypeDeserializer.PopulateFromMap（对象实例，IDictionary`2 keyValuePairs）在C:\src\ServiceStack\src\ServiceStack.Common\ServiceModel\Serialization\StringMapTypeDeserializer.cs:79中
[SerializationException:KeyValueDataContractDeserializer:转换为类型时出错：字符串未被识别为有效的日期时间。]
ServiceStack.ServiceModel.Serialization.StringMapTypeDeserializer.PopulateFromMap（对象实例，IDictionary`2个keyValuePairs）在C:\src\ServiceStack\src\ServiceStack.Common\ServiceModel\Serialization\StringMapTypeDeserializer.cs:95中
C:\src\ServiceStack\src\ServiceStack\ServiceHost\ServiceHost\RestPath.CreateRequest中的ServiceStack.ServiceHost.RestPath.CreateRequest（字符串pathInfo，字典'2 queryStringAndFormData，对象fromInstance）
C:\src\ServiceStack\src\ServiceStack\WebHost.Endpoints.RestHandler.GetRequest（IHttpRequest httpReq，IRestPath restPath）中的ServiceStack.WebHost.Endpoints.RestHandler.GetRequest
C:\src\ServiceStack\src\ServiceStack\ServiceStack\WebHost.Endpoints\RestHandler.ProcessRequest（IHttpRequest httpReq、IHttpResponse httpRes、String operationName）中的ServiceStack.WebHost.RestHandler.ProcessRequest（IHttpRequest httpRes、String operationName）：80
System.Web.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute（）+625
System.Web.HttpApplication.ExecuteStep（IExecutionStep步骤，布尔值&同步完成）+270

我知道这是一个错误，我知道它必须被捕获，但我想用我的错误代码和错误描述（人性化）来实现它

任何关于如何在异常写入自身响应（DebeugMode=true）或服务向客户端触发异常之前捕获异常的建议都会非常有用

Thnx

将自定义请求绑定器（或更高级的选项是在DTO上实现IRequiresRequestStream）添加到旁路ServiceStack的反序列化中

Thnx，以供您回复。它工作正常。当我的服务类从ServiceBase或RestServiceBase继承时，只需重写HandleException虚拟方法，就可以非常方便地实现类似的功能。
