如何在visual studio 2017 sdk中拦截项目保存事件?

在这种情况下,正确的方法是使用机具 IVsRunningDocTableEvents3 覆盖 OnBeforeSave

通过这种方式,我确切地知道项目何时被保存,并执行它所需要的。

前任。:

uint cookie;
var runningDocumentTable = (IVsRunningDocumentTable)GetGlobalService(typeof(SVsRunningDocumentTable));

runningDocumentTable.AdviseRunningDocTableEvents(new RunningDocTableEventsHandler(), out cookie);

using Microsoft.VisualStudio;
using Microsoft.VisualStudio.Shell;
using Microsoft.VisualStudio.Shell.Interop;

namespace YourProject
{
    internal class RunningDocTableEventsHandler : IVsRunningDocTableEvents3
    {

        #region Methods

        public int OnAfterFirstDocumentLock(uint docCookie, uint dwRDTLockType, uint dwReadLocksRemaining, uint dwEditLocksRemaining)
        {
            return VSConstants.S_OK;
        }

        public int OnBeforeLastDocumentUnlock(uint docCookie, uint dwRDTLockType, uint dwReadLocksRemaining, uint dwEditLocksRemaining)
        {
            return VSConstants.S_OK;
        }

        public int OnAfterSave(uint docCookie)
        {
            return VSConstants.S_OK;
        }

        public int OnAfterAttributeChange(uint docCookie, uint grfAttribs)
        {
            return VSConstants.S_OK;
        }

        public int OnBeforeDocumentWindowShow(uint docCookie, int fFirstShow, IVsWindowFrame pFrame)
        {
            return VSConstants.S_OK;
        }

        public int OnAfterDocumentWindowHide(uint docCookie, IVsWindowFrame pFrame)
        {
            return VSConstants.S_OK;
        }

        public int OnAfterAttributeChangeEx(uint docCookie, uint grfAttribs, IVsHierarchy pHierOld, uint itemidOld, string pszMkDocumentOld, IVsHierarchy pHierNew, uint itemidNew, string pszMkDocumentNew)
        {
            return VSConstants.S_OK;
        }

        public int OnBeforeSave(uint docCookie)
        {
            /////// MY CODE ////////
            return VSConstants.S_OK;
        }

        #endregion Methods
    }
}

根据您的需求,您需要实现IVsSolutionEvents3,以获得加载/卸载项目的通知。并通过SVsSolutionBuildManager服务将该对象注册为包初始化代码中的侦听器。

然后实现IVsHierarchyEvents以获得项目更改的通知,并在传递给IVsSolutionEvents3的OnAfterProjectOpen实现的IVsHierarchy对象上调用AdviseHierarchyEvents以注册事件侦听器对象。
