Complete List of Advanced C# 7 Features Web Developer Should Know

C# 7 recently added features focuses on simplification of code, performance, and consumption of data. These features are fully functional in visual studio 2017 but some features can also be used in Visual Studio “15” Preview 4.

So without further ado, let’s take a look at the new C# 7 features:

1. Out Variables

Out variables are used for returning multiple values from a function. Unlike the return statement which is capable of returning only one value from a function. Arguments are passed by reference throughout the keyword. Out variables were available prior to C# 7 but had following difference. Before C# 7, the Out variables were declared in a separate statement. Whenever there was a requirement of calling a method without parameters, then these variables were used as an out parameter in the method.

Example :

  • class Program
  • {
  • static void Main(string[] args)
  • {
  • //Out variable declaration in separate statement
  • int studentId;
