Remarks

Use the FindByText method to search the collection for a ListItem with a Text property that equals text specified by the text parameter. This method performs a case-sensitive and culture-insensitive comparison. This method does not do partial searches or wildcard searches. If an item is not found in the collection using this criteria, null is returned.
