Type.GetDefaultMembers() Method in C#

The Type.GetDefaultMembers() method in C# is used to search for the members defined for the current Type whose DefaultMemberAttribute is set.

Syntax

public virtual System.Reflection.MemberInfo[] GetDefaultMembers ();

Let us now see an example to implement the Type.GetDefaultMembers() method −

Example

using System;
using System.Reflection;
[DefaultMemberAttribute("subject")] public class Demo {
   public static void Main(){
      Type t = typeof(Demo);
      MemberInfo[] member = t.GetDefaultMembers();
      if (member.Length != 0){
         for (int i = 0; i < member.Length; i++)
         Console.WriteLine("{0}", member[i]);
      }
      else {
         Console.WriteLine("Default Member isn't there!");
      }
   }
   public void Name(String str) {}
   public String subject{
      get{
         return "Mathematics";
      }
   }
}

Output

This will produce the following output −

System.String subject

Let us now see another example to implement the Type.GetDefaultMembers() method −

Example

using System;
using System.Reflection;
[DefaultMemberAttribute("rank")] public class Demo {
   public static void Main(){
      Type t = typeof(Demo);
      MemberInfo[] member = t.GetDefaultMembers();
      if (member.Length != 0){
         for (int i = 0; i < member.Length; i++)
         Console.WriteLine("{0}", member[i]);
      }
      else {
         Console.WriteLine("Default Member isn't there!");
      }
   }
   public void Name(String str) {}
   public int rank{
      get{
         return 5;
      }
   }
}

Output

This will produce the following output −

Int32 rank
