Referencing ExcelCell and CellRange in C# and VB.NET

An Excel cell can be referenced in a variety of ways, by using either names or indexes. If using indexes, you can specify absolute or relative position.

The following example demonstrates various techniques for referencing ExcelCell and CellRange objects in C# and VB.NET, which can be used in GemBox.Spreadsheet component.
