Yesterday, I was looking for a way to get a list of all the primitive types in .NET during runtime.

Microsoft .NET’s definition of primitives is here:

https://msdn.microsoft.com/en-us/library/system.type.isprimitive%28v=vs.110%29.aspx

I found a Stack Overflow thread that provides an automated way to get a full list of primitive types from the Assembly during runtime.

List allTypes = typeof(string).Assembly.GetTypes()
.Where(t => t.IsPrimitive).ToList();

After testing, this works fine for my purposes.
