Are there any benefits to using curly braces for just a block of code (without using for, if, try etc)? [duplicate]

Answer 1

It is scoping the code. The problem with your experiment is that the outer scope conflicts with the inner scope. Consider:

public void ScopedFoo {
    {
      string foo = "foo";
    }
    {
      string foo = "bar";
    }
}
