GetProperty BindingFlags.IgnoreCase wont work without public and Instance in c#

Question

 Type t = typeof(T);
  t.GetProperty("Company")

If i write the below code it will give null

    Type t = typeof(T);
t.GetProperty("company", BindingFlags.IgnoreCase)

In the mean time if i write this works fine.Why is that so ?

Type t = typeof(T);
t.GetProperty("company", BindingFlags.IgnoreCase|BindingFlags.Public | BindingFlags.Instance)

The overload which doesn't take BindingFlags effectively defaults to BindingFlags.Public | BindingFlags.Static | BindingFlags.Instance. That's why it finds it in your first snippet.

If you do specify a BindingFlags, you have to specify all the relevant flags - which includes flags to say whether you want to see public members, whether you want to see non-public members, whether you want to see instance members, and whether you want to see static members.

When you just specify BindingFlags.IgnoreCase, you haven't said you want to see any of those, so it won't find anything.
