Add Excel Worksheet To Existing Workbook C# Tutorial
In this tutorial, we will take you step by step to explain the C# source code below, which helps to add a new sheet to an existing Excel workbook using Aspose.Cells for .NET. We will include sample code for each step to help you understand the process in detail.
Step 1: Define the Document Directory
To start, you need to set the directory path where your Excel file is located. Replace “YOUR DOCUMENT DIRECTORY” in the code with the actual path of your Excel file.
// The path to the documents directory.
string dataDir = "YOUR DOCUMENT DIRECTORY";
Step 2: Create a File Stream and Open the Excel File
Next, you need to create a file stream and open the Excel file using the FileStream class.
// Create a file stream containing the Excel file to open
FileStream fstream = new FileStream(dataDir + "book1.xls", FileMode.Open);
Step 3: Instantiate a Workbook Object
After opening the Excel file, you need to instantiate a Workbook object. This object represents the Excel workbook and offers various methods and properties to manipulate the workbook.
// Instantiate a Workbook object
// Open the Excel file via the file flow
Workbook workbook = new Workbook(fstream);
Step 4: Add a New Sheet to the Workbook
To add a new worksheet to the workbook, you can use the Worksheets.Add() method of the Workbook object. This method returns the index of the newly added sheet.
// Add a new sheet to the Workbook workbook
int i = workbook. Worksheets. Add();
Step 5: Set New Sheet Name
You can set the name of the newly added sheet using the Name property of the Worksheet object.
// Obtain the reference of the new sheet added by passing its sheet index
Worksheet worksheet = workbook.Worksheets[i];
// Define the name of the new sheet
worksheet.Name = "My Worksheet";
Step 6: Save the Excel File
Once you have added the new sheet and set its name, you can save the modified Excel file using the Save() method of the Workbook object.
// Save the Excel file
workbook.Save(dataDir + "output.out.xls");
Step 7: Close File Stream and Release Resources
Finally, it is important to close the file stream to release all the resources associated with it.
// Close file stream to release all resources
fstream.Close();
