 我知道如何遍历枚举属性列表，但我将如何遍历所有“选定”枚举属性？ 例如，如果有人做了Prop1 | Prop2 Prop1 | Prop2反对public enum Foo { Prop1; Prop2; Prop3 } public enum Foo { Prop1; Prop2; Prop3 } public enum Foo { Prop1; Prop2; Prop3 } ，我将如何实现这一目标？ 
 
 这是我现在拥有的： 
 
var values = Enum.GetValues(typeof(FileStatus)).Cast<FileStatus>();
foreach (var value in values)
{
}
 
 它遍历所有的枚举属性，但我只想循环那些“被选中”的。 
 
 更新：设置了[Flags]属性。 
 
 更新2：枚举包含大量的属性，我不能也不会键入/硬编码一个属性检查，而是我想动态地循环每个属性，并检查我的枚举实例Bar包含循环项目集。

 Iterate over values in Flags Enum?  13 answers  
 
 
 
 
I know how to loop through enum list of properties, but how would I loop through all "selected" enum properties? For example, if one did Prop1 | Prop2 against public enum Foo { Prop1; Prop2; Prop3 }, how would I achieve this?
 
This is what I have now:
 
var values = Enum.GetValues(typeof(FileStatus)).Cast<FileStatus>();
foreach (var value in values)
{
}
 
It loops through all enum properties, but I'd like to loop only the ones that were "selected".
 
Update: [Flags] attribute was set.
 
Update 2: The enum contains a large number of properties, I can't and won't type/hardcode a single property check, instead I want to dynamically loop through each of them and check if my enum instance Bar contains the looped item set.
