flags

Hi guys, i have this code:

[Flags]
public enum MyUriType {
ForParse,
ForDownload,
Unknown
}

and then:

MyUriType uriType = MyUriType.ForDownload;

but, I was wondering why this returns true:

if ((uriType & MyUriType.ForParse) == MyUriType.ForParse)

When it is not set in the second code group. Please advise.

Dynamic Type to do away with Reflection

In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
