C# 4.0 New Features: Optional and Named Parameters

Optional Parameters
• removes the ceremony of method overloads to assign default values
• static void GenerateChart(bool copyToWord = false)

Named Parameters
• call a method: GenerateChart(copyToWord: true);

Combining the two new features allow you to write concise code and not
specify values that are not needed in methods with a large number of arguments:

• Old: MethodA('A', null, null, null, false, null);
• New: MethodA(ArgA: 'A', ArgE: false);
