Code Inspection: 'if-return' statement can be re-written as 'return' statement

The conditional ?: (ternary) operator in C# is the most elegant way to execute one of two simple expressions depending on the value of a simple boolean expression.

Therefore, if JetBrains Rider encounters an if statement that returns control, immediately followed by another return, it suggests replacing those with a single return that makes use of the ?: operator.

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

            
string TryGetEntry(Dictionary<string, string> dict,
  string entry)
{
  if (dict.ContainsKey(entry))
    return dict[entry];
  return entry;
}

        

            
string TryGetEntry(Dictionary<string, string> dict,
  string entry)
{
  return dict.ContainsKey(entry) ? dict[entry] : entry;
}
