The case statement selects one statement for execution according to the evaluation of a condition.
This is the basic case statement syntax:
case expression of
case-clause...
otherwise-clauseopt
end
The case expression must return an integer value, an enumeration or a string value. First, the expression is evaluated, and a case clause is selected to match the expression result. A case clause is defined as a comma separated list of case labels:
case-label , ... : statement;
There are two kinds of case labels. This label kind is always available, no matter the type of the case expression:
expression
The second label kind is only available when the expression type is different from System.String:
expression .. expression
