以PushButton为例，网上的案例都是Uri引用本地图片，现将图片加载至Resources并调用。
关键语句：Uri uri = new Uri("pack://application:,,,/程序集名称;component/Resources/bj.png", UriKind.Absolute);
[Regeneration(RegenerationOption.Manual)]
[Journaling(JournalingMode.NoCommandData)]
public class Ribbon : IExternalApplication
{
Image image = Res.One_16;
public Result OnShutdown(UIControlledApplication application)
{
return Result.Succeeded;
}
public Result OnStartup(UIControlledApplication application)
{
application.CreateRibbonTab("无名氏制作");
RibbonPanel panel = application.CreateRibbonPanel("无名氏制作", "管道避让");
string assemblyName = string.Empty;//不可替用
//创建一个SplitButton
SplitButtonData splitButtonData = new SplitButtonData("管道避让", "单边避让");
SplitButton splitButton = panel.AddItem(splitButtonData) as SplitButton;
//创建一个pushButton加到SplitButton的下拉列表里
PushButton pushButton = splitButton.AddPushButton(new PushButtonData("AvoidMepCurve.OnesideCommand", "单边避让",
@"F:\Practice\AvoidMepCurve\AvoidMepCurve\bin\Debug\AvoidMepCurve.dll", "AvoidMepCurve.OnesideCommand"));
//@"F:\Practice\AvoidMepCurve\AvoidMepCurve\bin\Debug\AvoidMepCurve.dll"
//本地文件，添加图片
//Uri largeImage = new Uri(@"F:\Practice\AvoidMepCurve\AvoidMepCurve\ImageBox\One_32.png");
//Uri image = new Uri(@"F:\Practice\AvoidMepCurve\AvoidMepCurve\ImageBox\One_16.png");
//pushButton.LargeImage = new BitmapImage(largeImage);
//pushButton.Image = new BitmapImage(image);
//Resources添加图片
Uri largeImage = new Uri("pack://application:,,,/AvoidMepCurve;component/Resources/One_32.png", UriKind.Absolute);
Uri image = new Uri("pack://application:,,,/AvoidMepCurve;component/Resources/One_16.png", UriKind.Absolute);
pushButton.LargeImage = new BitmapImage(largeImage);
pushButton.Image = new BitmapImage(image);
pushButton.ToolTip = "为一端未连接的管道进行翻弯";
return Result.Succeeded;
