When concatenating strings in a single expression, the compiler seems to do the same optimization as with string interpolation. This means there’s no advantage in usingStringBuilder. Go with whatever is more readable. Aninteresting finding is that when the number of chars in the A,B,C, and ...
It supports standard formats available in .NET. The following code snippet formats an integer to a decimal. int price = 45; System.Text.StringBuilder bookPrice = new System.Text.StringBuilder("Book price:"); bookPrice.AppendFormat("{0:C} ", price); Console.WriteLine(bookPrice); ...
