Named arguments and optional parameters C# with Example
You can combine named arguments with optional parameters. Let see this method: public sealed class SmsUtil { public static bool SendMessage(string from, string to, string message, int retryCount = 5, object attachment = null) { // Some code } } When you want to call this method without set retryCount argument : var result = SmsUtil.SendMessage( from : "Cihan", to : "Yakar", message : "Hello there!", attachment : new object());
