Memory lifetime between static and instance method.

Question

Hi friends,

 

I need one clarification regarding static method. If am i create static method in the class when this memory release?

 

Eg:

 

public class A

{

public static int Add(int a,int b)

{

return a+b; 

} 

} 

 

Suppose, If i create  instance the method, when it will release the memory?

 

Eg:

 

If am i create static method in the class when this memory release.

Eg:

public class A

{

public int Add(int a,int b)

{

return a+b;

}

}

 

Which is best in memory.
