Code Inspection: Join local variable declaration and assignment

If you declare a local variable and initialize it later without any conditions, ReSharper suggests joining the declaration and the assignment in the place where the variable is first initialized. This removes unnecessary line and improves readability of your code.

Here is an example of a quick-fix suggested by this inspection:

            
int Bar()
{
  int myInt;
  //do something
  myInt = 3;
  // do something else
  return myInt - 1;
}

        

            
int Bar()
{
  //do something
  var myInt = 3;
  // do something else
  return myInt - 1;
}

        

When ReSharper joins the declaration and the assignment of your variable, it will use var or an explicit type depending on your preferences.
