Amit Mohanty · Answer

You can use SqlBulkCopy object to copy data from the CSV file to the database table. string csvPath = @"C:\YourCsvFile.csv"; string tableName = "YourTableName"; string connectionString = "Data Source=YourServer;Initial Catalog=YourDatabase;Integrated Security=True"; SqlConnection connection = new SqlConnection(connectionString); connection.Open(); // Create a DataTable to hold the CSV data. DataTable csvData = new DataTable(); using (OleDbDataAdapter adapter = new OleDbDataAdapter("SELECT * FROM [" + tableName + "]", @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + csvPath + ";Extended Properties='Text;HDR=YES;FMT=Delimited'")) { adapter.Fill(csvData); } // Use a SqlBulkCopy object to copy the data from the DataTable to the database table. using (SqlBulkCopy bulkCopy = new SqlBulkCopy(connection)) { bulkCopy.DestinationTableName = tableName; bulkCopy.WriteToServer(csvData); } connection.Close();
