C# 6.0 New Features - Expression-Bodied Methods
It’s a shorthand for writing methods. The body now can be written just like a Lambda expression as shown in Log2 method below:
public string Log(string timestamp, string application, string error, string status)
{
return string.Format("[Timestamp: \{timestamp}], Application: [\{application}], Error: [\{error}], Status [\{status}]");
}
public string Log2(string timestamp, string application, string error, string status) => string.Format("[Timestamp: \{timestamp}], Application: [\{application}], Error: [\{error}], Status [\{status}]");
It may come in handy for helper methods. The only benefit I can see is getting rid of opening and closing curly braces which generally don’t bother me much. But I know lots of people trying to avoid curly braces as much as possible. I’m sure this feature will be popular among them.
