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:

Suboptimal code

After the quick-fix

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); }
