Bastard Programmer from Hell
if you can't read my code, try converting it here[^]

if we want that variable outside the catch or final block we have to declare out side the try block .
If we want it only in try block then variable should be declared inside try block .

void SomeMethod(){
 {
  int a = 1;
  Console.WriteLine(a); // 1
 }
 {
  string a = "test";
  Console.WriteLine(a); // test
 }
}
