The reason for the "using" statement is to ensure that the object is always disposed correctly, and it doesn't require explicit code to ensure that this happens.

You are not going to learn how to program asking one question at a time on a message forum. You need to get yourself a book on programming and go through it, find some tutorials and work through them or take a class.

C#

using (SomeClass obj= new SomeClass())
{
    obj.DoSomething();
}

to

{ // limits scope of obj
    SomeClass obj= new SomeClass();
    try
    {
        obj.DoSomething();
    }
    finally
    {
        // Check for a null resource.
        if (obj!= null)
            // Call the object's Dispose method.
            ((IDisposable)obj).Dispose();
    }
}

Refer - using (C# Reference)[^].

Quote:

The using keyword has two major uses:

As a directive, when it is used to create an alias for a namespace or to import types defined in other namespaces. See using Directive.

As a statement, when it defines a scope at the end of which an object will be disposed. See using Statement.
