visual-studio-2015

Visual studio 2015 DTE2.VSIX CommandPackage中的文档异常,visual-studio-2015,vsix,Visual Studio 2015,Vsix,我试着做： Private _applicationObject As EnvDTE80.DTE2 = DirectCast(Me.ServiceProvider.GetService(GetType(SDTE)), DTE2) Dim docs As EnvDTE.Documents = _applicationObject.Documents Dim doc As EnvDTE.Document For Each doc In docs 'foobar() Next

我试着做：

  Private _applicationObject As EnvDTE80.DTE2 = DirectCast(Me.ServiceProvider.GetService(GetType(SDTE)), DTE2)
  Dim docs As EnvDTE.Documents = _applicationObject.Documents
  Dim doc As EnvDTE.Document
  For Each doc In docs
  'foobar()
  Next
但是在“文档”的第4行中有一个未知的COM异常。调用类的头/扩展名：

<PackageRegistration(UseManagedResourcesOnly:=True)>
<InstalledProductRegistration("#3110", "#3112", "1.0", IconResourceID:=3400)>
<ProvideMenuResource("Menus.ctmenu", 1)>
