Introduction

Working with Excel sheets is a common task in many programming projects. In C#, you can use the Microsoft.Office.Interop.Excel library to manipulate Excel files. One of the most important tasks is to determine the range of occupied cells in an Excel sheet. In this step-by-step guide, we will show you how to achieve this.

Step 1: Open an Excel file

To work with an Excel file in C#, you need to create a new instance of the Excel Application class and open the file. Here is the code:

using Microsoft.Office.Interop.Excel;

Application excel = new Application();
Workbook workbook = excel.Workbooks.Open(@"C:pathtofile.xlsx");

Step 2: Select a worksheet

Once you have opened the Excel file, you need to select the worksheet that you want to work with. Here is the code:

Worksheet worksheet = (Worksheet)workbook.Worksheets["Sheet1"];

Note that "Sheet1" is the name of the worksheet. You can replace it with the name of your own worksheet.

Step 3: Get the range of occupied cells

To get the range of occupied cells in the worksheet, you can use the UsedRange property. Here is the code:

Range usedRange = worksheet.UsedRange;

This will give you a Range object that represents the range of occupied cells in the worksheet.

Step 4: Get the address of the range

Finally, to get the address of the range, you can use the Address property of the Range object. Here is the code:

string address = usedRange.Address;

This will give you a string that represents the address of the range of occupied cells in the worksheet.

Conclusion

In this step-by-step guide, we have shown you how to get the range of occupied cells in an Excel sheet in C#. By following these steps, you can easily incorporate this functionality into your own C# projects. Remember to include the necessary using statements at the beginning of your code, and to release the resources when you are done working with the Excel file.
