Previously i need to locate the path of the open solution and for that i ask for a service that implements IVsSolution, so for this other problem I thing that there must be some service that provides me this information.

推荐答案

要澄清刚刚拿到viewhost，在堆垛机的回答，这里是你如何能得到当前编辑器查看完整的代码，并从那里ITextSelection，从在Visual Studio 2010中VSPackage的其他地方。特别是，我用这从一个菜单命令回调当前的选择。

To clarify "just get the viewhost" in Stacker's answer, here is the full code for how you can get the current editor view, and from there the ITextSelection, from anywhere else in a Visual Studio 2010 VSPackage. In particular, I used this to get the current selection from a menu command callback.

IWpfTextViewHost GetCurrentViewHost()
{
    // code to get access to the editor's currently selected text cribbed from
    // http://msdn.microsoft.com/en-us/library/dd884850.aspx
    IVsTextManager txtMgr = (IVsTextManager)GetService(typeof(SVsTextManager));
    IVsTextView vTextView = null;
    int mustHaveFocus = 1;
    txtMgr.GetActiveView(mustHaveFocus, null, out vTextView);
    IVsUserData userData = vTextView as IVsUserData;
    if (userData == null)
    {
        return null;
    }
    else
    {
        IWpfTextViewHost viewHost;
        object holder;
        Guid guidViewHost = DefGuidList.guidIWpfTextViewHost;
        userData.GetData(ref guidViewHost, out holder);
        viewHost = (IWpfTextViewHost)holder;
        return viewHost;
    }
}


/// Given an IWpfTextViewHost representing the currently selected editor pane,
/// return the ITextDocument for that view. That's useful for learning things 
/// like the filename of the document, its creation date, and so on.
ITextDocument GetTextDocumentForView( IWpfTextViewHost viewHost )
{
    ITextDocument document;
    viewHost.TextView.TextDataModel.DocumentBuffer.Properties.TryGetProperty(typeof(ITextDocument), out document);
    return document;
}

/// Get the current editor selection
ITextSelection GetSelection( IWpfTextViewHost viewHost )
{
    return viewHost.TextView.Selection;
}

下面是MSDN的文档进行的 IWpfTextViewHost ，的 ITextDocument 和的 ITextSelection 。

Here's MSDN's docs for IWpfTextViewHost, ITextDocument, and ITextSelection.
