Type.GetNestedType() Method in C#

The Type.GetNestedType() method in C# is used to get a specific type of nested within the current Type.

Syntax

Following is the syntax −

public Type GetNestedType (string name);
public abstract Type GetNestedType (string name, System.Reflection.BindingFlags bindingAttr);

Example

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

using System;
public class Demo {
   public static void Main(){
      Type type1 = typeof(Subject);
      try {
         Type type2 = type1.GetNestedType("AdvSubject");
         Console.Write("NestedType = "+ type2);
      }
      catch (ArgumentNullException e){
         Console.Write("{0}", e.GetType(), e.Message);
      }
   }
}
public class Subject{
   public class BasicSubject {
      //
   }
   public class AdvSubject {
      //
   }
}

Output

This will produce the following output −

NestedType = Subject+AdvSubject

Example

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

using System;
public class Demo {
   public static void Main(){
      Type type1 = typeof(Subject);
      try {
         Type type2 = type1.GetNestedType(null);
         Console.Write("NestedType = "+ type2);
      }
      catch (ArgumentNullException e){
         Console.Write("{0}", e.GetType(), e.Message);
      }
   }
}
public class Subject{
   public class BasicSubject {
      //
   }
   public class AdvSubject {
      //
   }
}

Output

This will produce the following output −

System.ArgumentNullException
