推荐答案

IVsUIShell vsShell =( IVsUIShell )serviceProvider.GetService( typeof ( SVsUIShell )))；
Guid guidPropBrowser = 新向导 ( ToolWindowGuids .PropertyBrowser);
vsShell.FindToolWindow(( 很细 ) __ VSFINDTOOLWIN .FTW_fForceCreate， ref guidPropBrowser，输出 frameProperties);

对象 objFrameSP;
frameProperties.GetProperty(( int ) __ VSFPROPID .VSFPROPID_SPFrame，输出 objFrameSP);
ServiceProvider frameSP = 新 ServiceProvider (( IOleServiceProvider )objFrameSP);
ITrackSelection trackSelection = frameSP.GetService( typeof ( STrackSelection ))) as ITrackSelection ; IOleServiceProvider定义为:

使用 IOleServiceProvider = Microsoft.VisualStudio.OLE.Interop. IServiceProvider ;

   IVsUIShell vsShell = (IVsUIShell)serviceProvider.GetService(typeof(SVsUIShell));
   Guid guidPropBrowser = new Guid(ToolWindowGuids.PropertyBrowser);
   vsShell.FindToolWindow((uint)__VSFINDTOOLWIN.FTW_fForceCreate, ref guidPropBrowser, out frameProperties);

   object objFrameSP;
   frameProperties.GetProperty((int)__VSFPROPID.VSFPROPID_SPFrame, out objFrameSP);
   ServiceProvider frameSP = new ServiceProvider((IOleServiceProvider)objFrameSP);
   ITrackSelection trackSelection = frameSP.GetService(typeof(STrackSelection)) as ITrackSelection;where IOleServiceProvider is defined with:

   using IOleServiceProvider = Microsoft.VisualStudio.OLE.Interop.IServiceProvider;
