Reading a .csv file into WPF application (C#)

Question

I\'ve just recently made a C# console application that could read a .csv file and write it to the console in a neat manner, however now I want to make it in WPF to make it e

Answer 1

First: Create a class that will hold the data per row.

public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public int ID { get; set; }
    public string Email { get; set; }

    public Person(string firstName, string lastName, int id, string email)
    {
        FirstName = firstName;
        LastName = lastName;
        ID = id;
        Email = email;
    }
}

Then create a function that will return a list of Persons from the CSV file:

public IEnumerable<Person> ReadCSV(string fileName)
{
    // We change file extension here to make sure it's a .csv file.
    // TODO: Error checking.
    string[] lines = File.ReadAllLines(System.IO.Path.ChangeExtension(fileName, ".csv"));

    // lines.Select allows me to project each line as a Person. 
    // This will give me an IEnumerable<Person> back.
    return lines.Select(line =>
    {
        string[] data = line.Split(';');
        // We return a person with the data in order.
        return new Person(data[0], data[1], Convert.ToInt32(data[2]), data[3]);
    });
}

Then configure your listview columns with the appropriate binding. Note that the x:Name property is the name you will use to access this listview in the .cs file of the form:

<ListView x:Name="ListViewPeople">
    <ListView.View>
        <GridView>
            <GridViewColumn Header="First name" Width="100" DisplayMemberBinding="{Binding Path=FirstName}"/>
            <GridViewColumn Header="Last name" Width="150" DisplayMemberBinding="{Binding Path=LastName}"/>
            <GridViewColumn Header="ID" Width="40" DisplayMemberBinding="{Binding Path=ID}"/>
            <GridViewColumn Header="Email" Width="200" DisplayMemberBinding="{Binding Path=Email}"/>
        </GridView>
    </ListView.View>
</ListView>

Lastly you bind the ItemsSource of the listview to the method returning the Person list:

public MainWindow()
{
    InitializeComponent();

    // We can access ListViewPeople here because that's the Name of our list
    // using the x:Name property in the designer.
    ListViewPeople.ItemsSource = ReadCSV("example");
}

CSV File
