2. Adding Worksheets to a Designer Spreadsheet


The process of adding worksheets to a designer spreadsheet is entirely same as that of the above approach except that the Excel file is already created and we need to open that Excel file first before adding worksheet to it. A designer spreadsheet can be opened by the Workbook class.
Example:
[C#]
//Creating a file stream containing the Excel file to be opened

FileStream fstream = new FileStream("C:\\book1.xls", FileMode.Open); 

//Instantiating a Workbook object

//Opening the Excel file through the file stream

Workbook workbook = new Workbook(fstream); 

//Adding a new worksheet to the Workbook object

int i = workbook.Worksheets.Add();



//Obtaining the reference of the newly added worksheet by passing its sheet index

Worksheet worksheet = workbook.Worksheets[i];



//Setting the name of the newly added worksheet

worksheet.Name = "My Worksheet";



//Saving the Excel file

workbook.Save(saveFileDialog1.FileName); 

//Closing the file stream to free all resources

fstream.Close();
