Hello)
Explain to me please - that's what does this error mean -
static void SearchPathBetweenCities(out string ReturnValue, CITY StartPoint, int n2 )
{
// ReturnValue += "\n";
n2 += 2;
// if (StartPoint.roadmass!=null) {}
}
error -
Error 2 The out parameter 'ReturnValue' must be assigned to before control leaves the current method
Thanks in advance))
