Question

我使用ServiceStack开发Rest服务。我的模型包含一个DateTime属性，问题从它开始。如果客户端发布错误的格式化日期值作为字符串，ServiceStack将触发一个异常“字符串未被识别为有效的DateTime。”

Stack Trace: 


[FormatException: String was not recognized as a valid DateTime.]
   System.DateTime.Parse(String s, IFormatProvider provider, DateTimeStyles styles) +6364458

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

任何建议对于如何在写入响应之前捕获异常（DebeugMode = true）或者服务向客户端发出异常都非常有帮助。

添加自定义请求活页夹（或更高级的选项是在您的DTO上实现IRequiresRequestStream）以绕过ServiceStack的反序列化。
