Question

How do I read the text of a resource txt file and put it into a TextBox in C# .net 4.0 WPF?
I have a TextBox in my form and a TXT file in my resources folder,
how do I put the text from the TXT file (including the line breaks, double spaces, etc) into the TextBox?

Please simplify the code for me because I’m a beginner in C#…
Thanks!

No difference reading file in WinForms or in WPF.
Simply add to you window TextBox and load file via System.IO.File class.

Example :

<Window x:Class="WpfApplication1.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="350" Width="525">
<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="*"/>
        <RowDefinition Height="auto"/>
    </Grid.RowDefinitions>
    <TextBox x:Name="tb" Margin="4"/>
    <Button Grid.Row="1" Content="Load file" x:Name="btnLoad" Click="btnLoad_Click" Width="60" HorizontalAlignment="Left" Margin="4"/>

</Grid>

and code behavior :

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
    }

    private void btnLoad_Click(object sender, RoutedEventArgs e)
    {
        tb.Text = File.ReadAllText(@"*path to file*");
    }
}
