我想要做的东西在C#中,我做的所有的时间在Ruby中,我不知道是最接近会是什么。
如果枚举不包含我的整数值的定义,我希望它默认为一定值。我能做到这一条线?
红宝石十岁上下的分配(两个例子):
namedStr = Enum.GetName(typeof运算(myEnum),enumedInt)|| 默认
或
namedStr = Enum.GetName(typeof运算(myEnum),enumedInt)
namedStr || =默认
解决方案
namedStr = Enum.GetName(typeof运算(myEnum),enumedInt)? 默认
I'm trying to do something in C# that I do all the time in Ruby, and I wondered what the closest thing would be.
If the Enum does not contain a definition for my integer value, I want it to default to a certain value. Can I do this in one line?
Ruby-ish assignment (two examples):
namedStr = Enum.GetName(typeof(myEnum), enumedInt) || "DEFAULT"
or
namedStr = Enum.GetName(typeof(myEnum), enumedInt)
namedStr ||= "DEFAULT"
解决方案
namedStr = Enum.GetName(typeof(myEnum), enumedInt) ?? "DEFAULT"
