Why would you leave the brackets in the code without a condition?-CodePudding

Why would you leave the open and close brackets in the code without the condition first? I've seen examples in C# where the code does compile when you have something like this:

{
  Console.WriteLine("Hey");
}

Is this just bad syntax? or something else?

CodePudding user response：

New brackets means new scope. For example if you want to create variable, which should exists only in specific part of code you can surround it with brackets:

{
   var a = 1;
   {
      var b = 2;
      //here 'a' and 'b' exist
   }
   //only 'a' exists
   {
      var b = 2;
      //again 'a' and 'b' exist
   }
   //again only 'a' exists
}
