wpf中如何在xaml中綁定cs中類的屬性

cs代碼：
/// <summary>
/// MainWindow.xaml 的交互邏輯
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
ContentGrid.DataContext = this;
this.Path = "數據綁定";
}

public string Path { get; set; }
}
XAML代碼：
<Grid x:Name="ContentGrid">
<TextBlock Text="{Binding Path}"></TextBlock>
</Grid>
