如何在.NET安装项目中添加卸载选项？

private void UninstallButton_Click(object sender, EventArgs e)
{
    string productCode = "{ProductCode}";
    string uninstallString = (string)Registry.GetValue(@"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\" + productCode, "UninstallString", null);
    if (!string.IsNullOrEmpty(uninstallString))
    {
        Process.Start(uninstallString);
    }
}
