Access cells data

There are 3 methods to access cell data:

Method 1: Using worksheet index property

Display “hello world” in A1 cell:

worksheet["A1"] = "hello world";

Get cell data via worksheet index property:

var text = worksheet["A1"];

Method 2: Set by cells instance

Cells property of worksheet is used to get cells instance:

var cell = worksheet.Cells["A1"];
cell.Data = "hello world";

The cells instance provides not only the Data property, but also many stuff of cells, such as formula, style, border and etc. See cell.

Method 3: Set cells data by using action

var action = new SetCellDataAction("A1", "hello world");

Changing cells data by using action will get the ability to revoke the changes by using Undo method.

Access cells instance

To access the cell instances, use Cells property of worksheet:

var cell = worksheet.Cells["A1"];
cell.Data = "hello world";

High Importance-20 The Cells property always return cell instance even no data and styles exist inside the cell. This is an safe and easy way to access cell instance, but it uses more memory when access to many cells.
