Question

string separator = " > ";

string retStr = "";

int count = 0;

foreach (string s in retList)
{
     count++;

     if(!string.IsNullOrEmpty(s))
     {
         if (count < retList.Count)
             retStr += s + separator;
         else
             retStr += s;

             //count < retList.Count ? retStr += s + separator : retStr += s;
      }
}

Out-commented line results in error: Only assignment, call, increment, decrement, and new object expressions can be used as a statement. Shouldnt that be eqvivalent to the if-case above?

Answer 1

using this

retStr = count < retList.Count ? retStr + s + separator : retStr + s;
