The following table describes the functions available for use with the Function element in code snippets.
Function | Description | Language |
|---|
GenerateSwitchCases(EnumerationLiteral) | Generates a switch statement and a set of case statements for the members of the enumeration specified by the EnumerationLiteral parameter. The EnumerationLiteral parameter must be either a reference to an enumeration literal or an enumeration type. | Visual C# |
ClassName() | Returns the name of the class that contains the inserted snippet. | Visual C# |
SimpleTypeName(TypeName) | Reduces the TypeName parameter to its simplest form in the context in which the snippet was invoked. | Visual C# |
The following example shows how to use the GenerateSwitchCases function. When this snippet is inserted and an enumeration is entered into the $switch_on$ literal, the $cases$ literal generates a case statement for every value in the enumeration.
