An implementation of the INameCreationService can have rules that define the parameters for valid names. This method can be implemented to validate a name and enforce those rules.
This method is similar to IsValidName, except that this method throws an exception if the name is invalid. This allows implementers to provide detailed information in the exception message.
The following code example provides an example INameCreationService..::.IsValidName method implementation that uses a string validation scheme that examines each character of the specified string to determine whether the specified string is a valid name. The method throws an exception if the string is not valid.
' Throws an exception if the specified name does not contain
' all valid character types.
