我正在为我的客户端/服务器休息调用使用一个很棒的包，名为Simple.OData.Client，但是我在从返回的错误中提取详细信息时遇到了问题。
有没有人知道将这些json响应反序列化为适当的异常类型的简单方法？
示例WebRequestException响应：

使用以下网站http://json2csharp.com/时，这比我想象的要容易一些。
我现在有以下＆＃34; ExceptionTranslator＆＃34;，我为我的项目实施的东西，但认为这个想法可能会帮助其他人。
public class WebRequestExceptionTranslator : IExceptionTranslator
{
public IExceptionModel Translate(Exception ex, out bool handled)
{
handled = false;
var wre = ex as WebRequestException;
if (wre != null)
{
var model = new ExceptionModel();
try
{
var jobject = JsonConvert.DeserializeObject<RootObject>(wre.Response);
if (jobject.error != null)
{
model.Message = jobject.error.message;
var inner = jobject.error.innererror;
string message = string.Empty;
while (inner != null)
{
message = inner.message.Replace("See the inner exception for details.", "Click Details for more information.");
inner = inner.internalexception;
if (inner == null)
model.Description = message;
else
model.Message = message;
}
handled = true;
return model;
}
}
catch
{
// this generated an exception, let another exception translator deal with it.
}
}
return null;
}
class Innererror
{
public string message { get; set; }
public string type { get; set; }
public string stacktrace { get; set; }
public Innererror internalexception { get; set; }
}
class Error
{
public string code { get; set; }
public string message { get; set; }
public Innererror innererror { get; set; }
}
class RootObject
{
public Error error { get; set; }
}
}
