What is the value of an anonymous unattached block in C#?

Question

In C# you can make a block inside of a method that is not attached to any other statement.

    public void TestMethod()
    {
        {
            string x          


        

Answer 1

This allows you to create a scope block anywhere. It's not that useful on it's own, but can make logic simpler:

switch( value )
{
    case const1: 
        int i = GetValueSomeHow();
        //do something
        return i.ToString();

    case const2:
        int i = GetADifferentValue();
        //this will throw an exception - i is already declared
 ...

In C# we can use a scope block so that items declared under each case are only in scope in that case:

switch( value )
{
    case const1: 
    {
        int i = GetValueSomeHow();
        //do something
        return i.ToString();
    }

    case const2:
    {
        int i = GetADifferentValue();
        //no exception now
        return SomeFunctionOfInt( i );
    }
 ...

This can also work for gotos and labels, not that you often use them in C#.
