With C# 13, you possibly can specify the ESC character far more concisely as proven within the following code snippet:
char esc="e";
Implicit index entry
With C# 13, the implicit “from the top” index operator ^ can now be utilized in object initializers. You should utilize ^ to specify a place in a group that’s relative to the top of the gathering.
For instance, take into account the next class.
class InitializerDemo
{
public int[] integers { get; set; } = new int[5];
}
Now you can use the next piece of code in C# 13 to reap the benefits of the index operator.
var arr = new InitializerDemo
{
integers =
{
[0] = 100,
[^1] = 1000
}
};
While you execute the above program, arr.Integers[0] can have the worth 100 whereas arr.Integers[4] can have the worth 1000. You should utilize the next line of code to show the values of the integer array on the console.
Console.WriteLine("The worth of arr.Integers[0] is {0} and arr.Integers[4] is {1}", arr.Integers[0], arr.Integers[4]);
Determine 2 exhibits the output on the console when the code is executed.
Determine 2. The implicit “from the top” index operator ^ in motion.
