What are the benefits of following this rule even if I am not wrapping an unmanaged resource,

public class HasDisposeMethod
{
      public HasDisposeMethod()
      {
      }
      public void UseFileStream()
      {
         using(FileStream newFile = new FileStream(@"c:\temp.txt", FileMode.Open))

The first statement means that you are going to declare an object and the second statement mean you are going to dispose an object. If you want to dispose an object then you assign null to that object.

Class class1 = null;<br />

Do developers consider it good practise to always initialise an instance to null when they are declared?

object obj;
object obj1 = null;
Console.WriteLine(obj == null);
Console.WriteLine(obj1 == null);
