Embedded local functions in C# 7.0

Occasionally it happens that we want to group related code within a function without creating another private function for that. C# 7.0 provides a neat way for that in the form of local functions which are functions within functions.

Consider the following example:

public class LocalFunctionsDemo
{
	public void RunDemo()
	{
		int GetDiff(DateTime first, DateTime second)
		{
			TimeSpan ts = (second - first).Duration();
			return Convert.ToInt32(ts.TotalDays);
		}

                int dayDiff = GetDiff(DateTime.UtcNow, DateTime.UtcNow.AddHours(10));
			
		Console.WriteLine(dayDiff);
	}
}
