GetProperty Method returns null C# .Net

问题

Can someone please explain, why does the GetProperty method in System.Type returns null for properties that are declared as 'internal' but works for 'public'.

internal class Test{      
  public string ALocal { get; set; }
  internal string SLocal { get; set; }}

var test = new Test();
var testType = test.GetType();

var aProp = testType.GetProperty("ALocal"); => returns string Type
var sProp = testType.GetProperty("SLocal"); => returns null

I understand differences between internal or public modifiers.

回答1:

GetProperty Method returns only public properties by default. You should include following flags

BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.Static 

to get internal type
