Description

Raises an EListError exception.

Call Error to raise an exception when an error occurs while working with a TList object. Error assembles an error message from the format string (or resource string) passed as the Msg parameter and the data value passed as the Data parameter, and then raises an EListError exception.

Call Error rather than adding a line such as

raise EListError.CreateFmt(MyMsg, iBadValue);

or

resourcestring sBadValueMessage = '%s not a valid list value';
  ...
EListError.Create(@sBadValueMessage, iBadValue);
throw EListError(MyMsg, iBadValue);

to reduce the code size of an application.
