How to decide a Type is a custom struct?

Question

For a Type, there is a property IsClass in C#, but how to decide a Type is a struct?

Although IsValueType is a ne

Answer 1

http://msdn.microsoft.com/en-us/library/bfft1t3c.aspx says: IsValueType is true if Type is in {bool, byte, char, decimal, double, enum, float, int, long, sbyte, short, struct, uint, ulong, ushort}.

http://msdn.microsoft.com/en-us/library/system.type.isprimitive%28v=vs.110%29.aspx says: IsPrimitive is true if Type is in {Boolean, Byte, SByte, Int16, UInt16, Int32, UInt32, Int64, UInt64, IntPtr, UIntPtr, Char, Double, and Single}.

Than for IsStruct you can use method like this:

public static bool IsStruct(this Type type)
{
    return type.IsValueType 
            && !type.IsPrimitive 
            && !type.IsEnum 
            && type != typeof(decimal);
}
