c# - 错误 : Word 2013 VSTO Cannot Handle Image in Header Formatted Behind or In Front of Text

Question

I am cross-posting this question from Microsoft Community因为我在那里没有得到任何回应，也许这里有人可以对此有所启发。

我注意到使用 VSTO 处理文档时 Word 2013 特有的问题。

文档在页眉或页脚中包含一个图像，其布局选项设置为“使用文本环绕”和“文本后面”或“文本前面”:

使用 VSTO，如果我打开文档然后尝试处理形状，我会收到以下异常:

The remote procedure call failed. (Exception from HRESULT: 0x800706BE)

我在这里上传了一个复制品:Word2013VstoImageFormattedInHeaderBug.zip

相关代码在WordFieldEnumerator.cs中:

private static bool ShapesWithinGroup(Shape shape)
{
    var result = false;
    try
    {
        // shape.GroupItems throws the exception
        if (shape.GroupItems != null && shape.GroupItems.Count > 0)
        {
            result = true;
        }
    }
    catch (UnauthorizedAccessException)
    {
        // This shape is not in a group - ignore
    }
    catch (Exception exception)
    {
        var exceptionString = exception.BuildExceptionString();
        Console.WriteLine(exceptionString);
        Console.WriteLine(exception.StackTrace);
        //throw;
    }

    return result;
}

这是完整的异常和堆栈跟踪:

无论我是否 try catch 异常都会引发异常，并且它会导致 Word 2013 崩溃:

这个bug在Word 2016上没有出现，我可以成功处理形状。但是，升级到 Office 2016 不是一种选择。我认为这需要 Office 2013 的修补程序才能修复错误。

我可以做些什么来让它在 Word 2013 上运行？我尝试了很多假定的修复，包括多次修复和重新安装 Office 2013，但都无济于事。

形状可以放置在页面上的任何位置，但它们始终附加到文本的锚定范围内。在遍历锚定到它的形状之前选择当前范围可能会解决 HRESULT 0x80010105 RPC_E_SERVERFAULT 异常。

在您的 GetAllFields() 方法中，在调用 ProcessShapes() 之前分别选择页眉和页脚的范围。

foreach (HeaderFooter header in section.Headers)
{
    if (header.LinkToPrevious) // || header.Index != WdHeaderFooterIndex.wdHeaderFooterFirstPage
    {
        continue;
    }

    header.Range.Select();

    // Add the fields in the header
    fields.AddRange(header.Range.Fields.Cast<Field>());

    // Add the fields in the shapes in the header
    var fieldsInShapes = ProcessShapes(header.Shapes.Cast<Shape>());
    fields.AddRange(fieldsInShapes);
}

foreach (HeaderFooter footer in section.Footers)
{
    if (footer.LinkToPrevious) // || footer.Index != WdHeaderFooterIndex.wdHeaderFooterFirstPage
    {
        continue;
    }

    footer.Range.Select();

    // Add the fields in the footer
    fields.AddRange(footer.Range.Fields.Cast<Field>());

    // Add the fields in the shapes in the footer
    var fieldsInShapes = ProcessShapes(footer.Shapes.Cast<Shape>());
    fields.AddRange(fieldsInShapes);
}

不知道对你有没有帮助？ (我不是 Word 互操作专家..)
