Welcome to FoLearn
In this tutorial, I'll show you how to access data in text files using the c# language
To play the demo, you should export data from the customer table to a text file
We will use the Northwind database to play the demo
If you don't have the Northwind database you can download it from the http://foxlearn.com website
Drag the Button and DataGridView from your visual toolbox into your windows forms application
then design a simple UI that allows you to open a text file and fill data into the DataGridView
Right click on your project, then create a customer class
Next, You need to add properties corresponding to the columns in the customer table
To populate the DataGridView, you should add a bindingsource to your DataGridView
The BindingSource component is designed to simplify the process of binding controls to an underlying data source
The Open File Dialog component allows users to browse the folders of their computer or any computer on the network, and select one or more files to open
The dialog box returns the path and name of the file the user selected in the dialog box
To access data in a text file, you need to read all the lines in the text file, and then split the data into an array with a comma
Next, we will use the loop to add the customer object to the customer list
