Read Excel file from ASP.NET

To read an Excel file from an ASP.NET application, you can use the ExcelDataReader library. Here's an example of how you can read an Excel file in ASP.NET:

Install the ExcelDataReader and its associated dependencies via NuGet Package Manager.

Import the required namespaces:

using ExcelDataReader; using System.IO;

Create a method to read the Excel file:

protected void ReadExcelFile(string filePath) { // Create a new stream to read the Excel file using (FileStream stream = File.Open(filePath, FileMode.Open, FileAccess.Read)) { // Create an ExcelDataReader object to read the Excel file using (IExcelDataReader reader = ExcelReaderFactory.CreateReader(stream)) { // Read the Excel file content DataSet dataSet = reader.AsDataSet(); // Retrieve the first sheet of the Excel file DataTable dataTable = dataSet.Tables[0]; // Perform operations with the DataTable, such as accessing rows and columns foreach (DataRow row in dataTable.Rows) { foreach (DataColumn column in dataTable.Columns) { // Access the cell value var cellValue = row[column]; // Perform necessary operations with the cell value // ... } } } } }

Call the ReadExcelFile method, passing the path to your Excel file as a parameter:

string filePath = "path_to_your_excel_file.xlsx"; ReadExcelFile(filePath);

Make sure to replace "path_to_your_excel_file.xlsx" with the actual path to your Excel file.

This code will read the content of the Excel file and store it in a DataSet. You can then access individual sheets and perform operations on the data using the DataTable object.
