Change Button name via WPF code?

Question

I’m looking to access a control in WPF to access the properties of it and modify.

However, I can’t find much approach to Wpf currently.

What I want to do, for example, is change the name of a button for any name.

XAML

<Button Content="Button" HorizontalAlignment="Left" VerticalAlignment="Top" Width="75" Margin="362,31,0,0" Height="20" Click="Button_Click" RenderTransformOrigin="0.5,0.5">
        <Button.RenderTransform>
            <TransformGroup>
                <ScaleTransform/>
                <SkewTransform/>
                <RotateTransform Angle="360.279"/>
                <TranslateTransform/>
            </TransformGroup>
</Button.RenderTransform>

At XAML.CS, I don’t know how to access Button.

This is not the most appropriate way to do this (the correct would be using Binding, but it is not the focus of the question), but here it is:

Set the name of your button in the file .xaml of his Window through the attribute x:Name

<Button x:Name="btnMyButton" Content="OK" Width="200" Height="30" ></Button>

With this, you can access it through the file .xaml.cs of his Window calling the button by the name previously created btnMyButton:

public MainWindow()
{
    InitializeComponent();

    // Altera o conteúdo do botão
    btnMyButton.Content = "Clique aqui";

    // Altera o comprimento do botão
    btnMyButton.Width = 100;

    // Altera a altura do botão
    btnMyButton.Height = 30;

    // Define um evento ao clicar no botão
    btnMyButton.Click += BtnMyButton_Click;
}

private void BtnMyButton_Click(object sender, RoutedEventArgs e)
{
    throw new NotImplementedException();
}
