Description
Returns the value of an enumerated type constant given its string representation.
Use GetEnumValue to convert the string that represents an enumerated value into the corresponding integer that is its implemented value.
TypeInfo is the type information record that describes the enumerated type. You can obtain the type information for a type by calling the TypeInfo function in Delphi or using the __delphirtti operator in C++.
The Name argument should contains a string representation of an enumerated type constant. GetEnumValue uses a case-insensitive match.
GetEnumValue returns the corresponding integer value, or -1 if Name does not match any constant in the supplied TypeInfo.
Sample syntax:
I := System.TypInfo.GetEnumValue(TypeInfo(TAbc), 'abcSomeOption');
