有谁知道 System 或 System.Core 中比较运算符的 .NET 枚举？
System 或 System.Core 中是否有包含所有 ComparisonOperator 的枚举？
我刚刚写了下面的枚举，但它似乎是一个很常见的东西，可能已经存在了。
public enum ComparisonPredicate
{
Equal,
Unequal,
LessThan,
LessThanOrEqualTo,
GreaterThan,
GreaterThanOrEqualTo
}
我在 System.Web.UI 中找到了一个，但是为该 http://msdn.microsoft.com/en -us/library/system.web.ui.webcontrols.validationcompareoperator(v=VS.100).aspx
另外，我已经看过 ExpressionType，但我不想要范围那么广的东西
Is there an enum in System or System.Core that has all the ComparisonOperators?
I just wrote the following enum, but it seems like a common enough thing that one might already exist.
public enum ComparisonPredicate
{
Equal,
Unequal,
LessThan,
LessThanOrEqualTo,
GreaterThan,
GreaterThanOrEqualTo
}
I found one in System.Web.UI, but it would be more than silly to introduce a dependency for that http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.validationcompareoperator(v=VS.100).aspx
Also, I already looked at ExpressionType, but I don't want something with that broad of a scope

据我所知这样的事情不存在。目前，您最好使用自己的。
AFIK such a thing does not exist. You are probably better off using your own, for now.
这是 Google 上的最高结果，但由于我是在 2018 年写这篇文章，并且在 .Net 4.5+ 领域，正确的答案是：
请参阅 learn.microsoft.com/en-us/dotnet/api/system.enum.equals?view=netframework- 4.7.2
This is the top result on Google however since I am writing this in 2018, and in the area of .Net 4.5+, the correct answer is:
See learn.microsoft.com/en-us/dotnet/api/system.enum.equals?view=netframework-4.7.2
有点晚了，但是.Net 3.5在
System.Linq.Expressions中引入了ExpressionType枚举，请参阅http://msdn.microsoft.com/en-us/library/bb361179(v=vs.110).aspx 了解更多详细信息。A bit late, but .Net 3.5 introduced the
