Why does C# allow {} code blocks without a preceding statement?

Question

Why does C# allow code blocks without a preceding statement (e.g. if, else, for, while)?

void Main()
{
           


        

Answer 1

I consider {} as a statement that can contain several statements.

Consider an if statement that exists out of a boolean expression followed by one statement. This would work:

if (true) Console.Write("FooBar");

This would work as well:

if (true)
{
  Console.Write("Foo");
  Console.Write("Bar");
}

If I'm not mistaken this is called a block statement.

Since {} can contain other statements it can also contain other {}. The scope of a variable is defined by it's parent {} (block statement).

The point that I'm trying to make is that {} is just a statement, so it doesn't require an if or whatever...
