In C#, you can use the comma to declare more than one local variable in a statement. The following displays the same −
int a = 20, b = 70, c = 40, d = 90;
Example
Let us see an example in which we are declaring multiple local variables. Below four variable is declared and initialized in the same statement.
using System;
class Demo {
static void Main() {
int a = 20, b = 70, c = 40, d = 90;
Console.WriteLine("{0} {1} {2} {3}", a, b, c, d);
}
}Output
20 70 40 90
