Question

Using reflection I’d like to retrieve only the built-in data type properties from a C# object. Is there a better way to do that then using a bunch of || (ors) in a Where method specifying the types I am interested in?

Type sourceType = typeof(TSource);

var props = sourceType.GetProperties()
    .Where(pi => pi.PropertyType == typeof(int)
              || pi.PropertyType == typeof(string));    // .... etc.

Answer 1

Are you looking for integral types to the BCL? Or value types only? (IE integer, char, etc)

If so, you could test for pi.PropertyType.IsPrimitive() and then test for string type as part of the or clause…

var props = sourceType.GetProperties()
    .Where(pi => .PropertyType.IsPrimitive
              || pi.PropertyType == typeof(string))
