I want to know details about the type of a field by reflection.
I know I can find out that it is a value type with Type.IsValueType. But from there how do I know it is a number? A fixed point number? Signed or unsigned??
Is there anything like Type.IsSigned?
There aren't that many numeric types that are unsigned, so why not compose a list of that:
if (new Type[] { typeof(ushort), typeof(uint), typeof(ulong), typeof(byte) }.Contains(type))
{
// unsigned.
}
Or if you just want to compare the value (here o):
if (o is ushort || o is uint || o is ulong || o is byte)
{
// unsigned.
}
