Delete Excel Worksheet By Name C# Tutorial
In this tutorial, we will guide you step by step to explain the C# source code below, which can delete an Excel worksheet using Aspose.Cells for .NET using its name. 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: Delete a Worksheet by Name
To remove a worksheet from its name, you can use the RemoveAt() method of the Worksheets object of the Workbook object. The name of the worksheet you want to delete must be passed as a parameter.
// Delete a worksheet using its sheet name
workbook.Worksheets.RemoveAt("Sheet1");
Step 5: Save the Workbook
Once you have deleted the worksheet, you can save the modified Excel workbook using the Save() method of the Workbook object.
// Save the Excel workbook
workbook.Save(dataDir + "output.out.xls");
