ASP.NET MVC3 HttpStatusCodeResult StatusDescription - 指定的参数超出了有效值的范围

Question

时遇到错误

由于某种原因，我在尝试在我的 MVC3 应用程序中返回new HttpStatusCodeResult(500, statusDescription);

。它会因错误而爆炸

Specified argument was out of the range of valid values.
Parameter name: value
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.

Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.372 

如果我将结果更改为 return new HttpStatusCodeResult(500, "statusDescription");

然后它就会正常工作，状态描述是否有某种长度限制？
