Examples

The following code sample demonstrates setting the Cases property of a Switch<T> activity.

// check if the number is ok...
new Switch<int>()
{
    DisplayName = "Verify Value from User",
    Expression = ExpressionServices.Convert<int>( env => numberFromUser.Get(env).CompareTo(numberToGuess.Get(env)) ),
    Cases =
    {
        { 0, new Assign<bool>()
            {
                To = new OutArgument<bool>(finished),
                Value = true
            }
        },
        {  1, new WriteLine() { Text = "    Try a lower number number..." } },
        { -1, new WriteLine() { Text = "    Try a higher number" } }
    }
}

Remarks

When the activity executes, the case that is executed is the first case whose key matches the Expression property.
