c# - VS 2010 错误 "Value to add was out of range. Parameter name: value "

Question

我遇到了一个奇怪的问题。我的 Web 应用程序抛出错误“要添加的值超出范围参数名称:值”。现在这不是我每次运行程序时都会出现这种情况。有时显示错误，有时运行没有问题(未完成任何更改)。错误下方给出的堆栈跟踪不清楚(至少对我而言)。有人遇到过这种问题吗？

错误详情

要添加的值超出范围。参数名称:值说明:在执行当前 Web 请求期间发生未处理的异常。请查看堆栈跟踪以获取有关错误及其在代码中的来源的更多信息。

只是猜测:由于异常似乎是从您无法控制的代码中抛出的，因此导致错误的不是您的代码。但是，这可能是您的系统设置。例如，由于某些奇怪的原因 System.DateTime.Add(Double value, Int32 scale) 被调用时带有这样的参数，即 MSDN states ,

The resulting DateTime is less than MinValue or greater than MaxValue.

是否有可能您计算机上的时间现在设置为某个令人难以置信的高值？例如，接近 23:59:59.9999999, December 31, 9999。或者可能是低值，接近于 00:00:00.0000000, January 1, 0001。因此，由于某些原因，编译器选择了当前日期并需要为其添加一些时间跨度，这会导致您的错误。

只是一个大胆的猜测，但也许......

更新

可以找到System.Web.Compilation.CodeDirectoryCompiler.GetCodeDirectoryAssembly方法的代码here .代码中有一行

DateTime waitLimit = DateTime.UtcNow.AddMilliseconds(3000); 

那是唯一可能抛出此类异常的地方(如果我正在查看的版本与您的环境相同)。因此，它会为您计算机上设置的奇怪时间投更多票。
