C# 如何从IDifferenceViewer'；左视图是什么？

我希望能够编辑来自IDifferenceViewer的左侧ITextView（

LeftView

属性）的ITextBuffer，但一旦构建完成，调用

IsReadOnly（）

时，LeftView即为只读。如何允许LeftView的ITextBuffer可编辑

var diffService = (IVsDifferenceService)_serviceProvider.GetService(typeof(SVsDifferenceService));

//roles don't seem to do anything...
string roles = null; //$"{PredefinedTextViewRoles.Editable},{PredefinedTextViewRoles.PrimaryDocument},{PredefinedTextViewRoles.Document},{PredefinedTextViewRoles.Interactive},DIFF";
var frame = diffService.OpenComparisonWindow2(filePath1, filePath2,
    $"Your version vs Other version",
    filePath1 + Environment.NewLine + filePath2,
    filePath1,
    filePath2, null, null, 0);
var diffViewer = GetDiffViewer(frame);
diffViewer.LeftView.TextBuffer.IsReadOnly(0, false); // true!

您所指的LeftTextView是指。在IdifferenceViewer界面中，似乎只存在LeftText。@LanceLi MSFT我更新了帖子，使其更加清晰——属性名称是

LeftView

Hi brianc，我正试图让一位更具经验的人参与进来，帮助研究它。请耐心等待答复。

static IDifferenceViewer GetDiffViewer(IVsWindowFrame frame) {
            ThreadHelper.ThrowIfNotOnUIThread();
            return ErrorHandler.Succeeded(frame.GetProperty((int)__VSFPROPID.VSFPROPID_DocView, out object docView))
                ? (docView as IVsDifferenceCodeWindow)?.DifferenceViewer : null;
}
