Code Inspection: Convert 'if' to '||'

An If statement can be rewritten using the conditional OR operator, provided that it’s a bool value that you modify depending on the result of the If statement.

Below, the Contains method returns bool, so you can assign the result of the method directly to a bool variable a. JetBrains Rider provides a quick-fix on If, which replaces If with the conditional OR operator to simplify the code:

            
private static void TestMethod(string s, bool b)
{
  bool a = b;
  if (!s.Contains("."))
  {
    a = true;
  }
  Console.WriteLine(a);
}

        

            
private static void TestMethod(string s, bool b)
{
  bool a = b || !s.Contains(".");
  Console.WriteLine(a);
}
