c# - 将多个图像添加到特定位置的 Word 文档 OpenXML

Question

我正在使用 Office Open XML，我必须在特定点添加图像。在文件上我有一个“标签”，所以我可以很好地找到它。但是，当我添加多个图像时，它会损坏文件。

这是我的代码:(修改自 https://msdn.microsoft.com/en-us/library/office/bb497430.aspx )

使用:

using DocumentFormat.OpenXml.Wordprocessing;
using A = DocumentFormat.OpenXml.Drawing;
using DW = DocumentFormat.OpenXml.Drawing.Wordprocessing;
using PIC = DocumentFormat.OpenXml.Drawing.Pictures;

我的主要:

private const string Loc = @"D:\Documents\2-Mass Output.docx";
static void Main(string[] args)
{
    var images = new[]
    {
        @"D:\Documents\NPL.bmp",
        @"D:\Documents\NVT.bmp",
        @"D:\Documents\MPL.bmp",
        @"D:\Documents\MVT.bmp"
    };
    var tags = new[]
    {
        "NormalGraph1",
        "NormalGraph2",
        "MisGraph1",
        "MisGraph2"
    };

    InsertPicture(Loc, images, tags);
}

方法如下:

/// <summary>
/// Inserts a picture in a paragraph with a specific text
/// </summary>
/// <param name="document">Where the file is located</param>
/// <param name="fileName">Name of the image file</param>
/// <param name="tag">Insert Image in the first paragraph that contains this text</param>
public static void InsertPicture(string document, string[] fileName, string[] tag)
{
    using (var wordprocessingDocument = WordprocessingDocument.Open(document, true))
    {
        var mainPart = wordprocessingDocument.MainDocumentPart;

        for (var i = 0; i < fileName.Length; i++)
        {
            var imagePart = mainPart.AddImagePart(ImagePartType.Bmp);
            using (var stream = new FileStream(fileName[i], FileMode.Open))
            {
                imagePart.FeedData(stream);
            }
            AddImageToBody(wordprocessingDocument, mainPart.GetIdOfPart(imagePart), tag[i]);
        }
    }
}

private static void AddImageToBody(WordprocessingDocument wordDoc, string relationshipId, string tag)
{
    // Define the reference of the image.
    var element =
            new Drawing(
                new DW.Inline(
                    new DW.Extent { Cx = 5d.Inches(), Cy = 2.66.Inches() }, // Width and Height of the image in inches. 1" = 1000000L
                    new DW.EffectExtent
                    {
                        LeftEdge = 0L,
                        TopEdge = 0L,
                        RightEdge = 0L,
                        BottomEdge = 0L
                    },
                    new DW.DocProperties
                    {
                        Id = 1U,
                        Name = tag // Make sure all of the images have a different name
                    },

                                    new PIC.NonVisualPictureDrawingProperties()),

                                            {
                                                Uri = "{28A0092B-C50C-407E-A947-70E740481C1C}"
                                            })
                                    )
                                    {
                                        Embed = relationshipId,
                                        CompressionState = A.BlipCompressionValues.Print
                                    },
                                    new A.Stretch(
                                        new A.FillRectangle())),
                                new PIC.ShapeProperties(
                                    new A.Transform2D(
                                        new A.Offset { X = 0L, Y = 0L },
                                        new A.Extents { Cx = 5d.Inches(), Cy = 2.66.Inches() }), // Width and Height of the image in inches. 1" = 1000000L
                                    new A.PresetGeometry(
                                        new A.AdjustValueList()
                                    )
                                    { Preset = A.ShapeTypeValues.Rectangle }))
                        )
                        { Uri = "http://schemas.openxmlformats.org/drawingml/2006/picture" })
                )
                {
                    DistanceFromTop = 0U,
                    DistanceFromBottom = 0U,
                    DistanceFromLeft = 0U,
                    DistanceFromRight = 0U,
                    EditId = "50D07946"
                });

    // Append the reference to the specific paragraph that contains the 'tag'.
    wordDoc.MainDocumentPart.Document.Body.Elements<Paragraph>().FirstOrDefault(f => f.InnerText.Contains(tag))?.AppendChild(new Paragraph(new Run(element)));
}

根据Word将英寸转换为英寸的函数:

private static long Inches(this double size)
{
    return (long) (size*1000000);
}

编辑: 这里是 header1.xml 的内容。添加图像前后它们是一样的。

Answer 1

我可以看到您发布的代码有 3 个问题，但我不确定为什么您只在输出多张图像时才会看到错误。

第一个问题是DocProperties 的Id。 Id 属性在文档中的所有 DocProperties 中应该是唯一的。

new DW.DocProperties
{
    Id = 1U, //this should be unique amongst ALL DocProperties within the document
    Name = tag // Make sure all of the images have a different name
},

第二期很相似；每个 NonVisualDrawingProperties 的 Id 在每个 NonVisualDrawingProperties 实例中也应该是唯一的。

请注意，在这两种情况下，您都需要这些值与 header 中已存在的值不同。从您发布的 header XML 中，您可以看到您已经拥有这些属性的实例:

<wp:docPr id="1" name="NormalGraph2" />

和

<pic:cNvPr id="0" name="NormalGraph2.bmp" />

最后，我可以看到的第三个问题是在您添加 元素 的代码中。在该代码中，您将找到包含 标记 的 Paragraph，然后将 Paragraph 附加到现有 Paragraph。 Paragraph 不允许是另一个 Paragraph 的子项。相反，您应该将 Run 添加到现有的 Paragraph 中，如下所示:

wordDoc.MainDocumentPart.Document.Body.Elements<Paragraph>().FirstOrDefault(f => f.InnerText.Contains(tag))?.AppendChild(new Run(element));

或者，如果您需要单独的段落，则在标记 Paragraph 之后针对相同的 Parent 节点添加 Paragraph:

var tagNode = wordDoc.MainDocumentPart.Document.Body.Elements<Paragraph>().FirstOrDefault(f => f.InnerText.Contains(tag));
if (tagNode != null)
{
    tagNode.Parent.InsertAfter(new Run(element), tagNode);
}
