如何用vs2010 调试这个程序

namespace c
{
///

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

    private void Window_Loaded(object sender, RoutedEventArgs e)
    {
        System.Drawing.FontFamily[] families =  System.Drawing.FontFamily.Families;
        foreach (System.Drawing.FontFamily family in families)
            comboBox1.Items.Add(family.Name);

    }

    private void comboBox1_SelectionChanged(object sender, SelectionChangedEventArgs e)
    {
        label1.FontFamily = new FontFamily(comboBox1.SelectedItem.ToString());
    }
}

}

新建一个wpf程序，添加comboBox
复制代码进去，运行

这个代码的作用是在下拉框里面列举系统里安装的字体。

还要放一个label，用label展示选择的字体的样式。
