Example

using System;

namespace Samples
{
  public class GCSample
  {
    private readonly string message;
    private int i;
    public GCSample(string s, int i)
    {
      message = s;
      this.i = i;
    }
    ~GCSample()
    {
      Console.WriteLine("In Finalize for \"{0}\"", message);
      if(--i > 0)
        GC.ReRegisterForFinalize(this);
    }
    public static void Main()
    {
      GCSample g1 = new GCSample("First", 5);
      GCSample g2 = new GCSample("Second", 5);
      GC.SuppressFinalize(g2);
      g1 = g2 = null;
      GC.WaitForPendingFinalizers();
    }
  }
}

The output is

In Finalize for "First"
