Multiple command parameters wpf button object

Question

How can I send multiple parameters from Button in WPF? I am able to send single parameter which is value of TextBox properly. Here is the code.

XAML

<TextBox Grid.Row="1" Height="23" HorizontalAlignment="Left" Margin="133,22,0,0"     Name="textBox1" VerticalAlignment="Top" Width="120" />
<Button Content="Button" Grid.Row="1" Height="23" Command="{Binding Path=CommandClick}" CommandParameter="{Binding Text,ElementName=textBox1}" HorizontalAlignment="Left" Margin="133,62,0,0" Name="button1" VerticalAlignment="Top" Width="75" />

Code behind

public ICommand CommandClick { get; set; }

this.CommandClick = new DelegateCommand<object>(AddAccount);

private void AddAccount(object obj)
{
    //custom logic
}

You can only send one parameter as the CommandParameter.

A better solution is typically to just bind the TextBox and other controls to multiple properties in your ViewModel. The command would then have access to all of those properties (since it's in the same class), with no need for a command parameter at all.
