C# Switch Position Explained

In C#, the switch statement determines which branch of code to execute based on the value of an expression. Different case labels can be used in the switch statement to match different values. When the value of the expression is equal to the value of a case label, the code in that case branch will be executed. If there is no matching case label, the default label can be used to execute default code.

Here is a simple example demonstrating how to use a switch statement to determine position.

int position = 1;

switch (position)
{
    case 1:
        Console.WriteLine("在第一位置");
        break;
    case 2:
        Console.WriteLine("在第二位置");
        break;
    case 3:
        Console.WriteLine("在第三位置");
        break;
    default:
        Console.WriteLine("位置未知");
        break;
}

In the above example, if the value of the expression ‘position’ is 1, the code of the first case branch will be executed, and “at position one” will be outputted. If the value of ‘position’ is changed to 2 or 3, the code of the second and third case branches will be executed respectively. If the value of ‘position’ is not 1, 2, or 3, the code of the default branch will be executed, and “unknown position” will be outputted.
