I am using someone’s SDK, but the document does not tell me something is a struct or a class.
How can I find out that? typeof or GetType just show the name.
I’d like find out that in the IDE(VS2010); approaches through coding are also acceptable.
Programmatically speaking, you can use
GetType().IsValueType.From Visual Studio, you can also check by using the Object Browser (shown below, found under View -> Object Browser).
