在Word Open SDK + dotnet核心中添加图像

问题描述

我正在尝试使用dotnet core和Open SDK库将图像添加到word文档中。遵循与MSDN文章完全相同的指示。该代码运行正常，但是在尝试打开文档时却说该文档已损坏。

Microsoft Doc

使用OpenSDK生产力工具并验证了文档。显示此错误

已确认图像类型相同。无法理解出了什么问题。

    private const string RefrenceKeyWord = "rId";
    static void Main(string[] args)

        Int64Value imageHeight = 3820795L;
        //using (var image = new Bitmap(fileName))
        //{
        //    imageWidth = image.GetWidthInEMUs() / 10;
        //    imageHeight = image.GetHeightInEMUs() / 10;
