C#采用OpenXml给word里面插入图片

本文实例讲述了C#采用OpenXml给word里面插入图片的方法,分享给大家供大家参考。具体分析如下:
首先需要指出的是在MSDN官网有完整的OpenXML教程,虽然是全英文的不过还是很有帮助的。
注,原来摘抄代码里面没有模板,在copy过来发现插入word中的图片大小不一样,我们如何查找设置图片大小带代码的那一块,建议自己用在word里面插入一张图片,通过OpenXml Tools 反编译出C#代码,然后改变图片的大小,再次反编译。
使用byeond compare 【http://www.scootersoftware.com/ 下载地址】比较C#代码,就会发现是因为new DW.Extent() { Cx = 990000L, Cy = 792000L} 是因为这段设置造成的。以后其实很多地方都可以借助OpenXml Tools反编译来进行对比。查看设置样式的属性位置。

示例代码如下:
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using DocumentFormat.OpenXml; using DocumentFormat.OpenXml.Packaging; using DocumentFormat.OpenXml.Wordprocessing; using System.IO; using DW = DocumentFormat.OpenXml.Drawing.Wordprocessing; using PIC = DocumentFormat.OpenXml.Drawing.Pictures; using A = DocumentFormat.OpenXml.Drawing; namespace AddPictureIntoWord { public class Program { public static void Main(string[] args) { string picPath = "u=639047729,3872612606&fm=11&gp=0.bmp"; string filePath = "Test.docx"; AddPictureIntoWord(filePath, picPath); } public static void AddPictureIntoWord(string filePath, string picturePath) { using (WordprocessingDocument doc = WordprocessingDocument.Open(filePath, true)) { string picType = picturePath.Split('.').Last(); ImagePartType imagePartType; ImagePart imagePart = null; // 通过后缀名判断图片类型, true 表示忽视大小写 if (Enum.TryParse<ImagePartType>(picType, true, out imagePartType)) { imagePart = doc.MainDocumentPart.AddImagePart(imagePartType); } imagePart.FeedData(File.Open(picturePath, FileMode.Open)); // 读取图片二进制流 AddImageToBody(doc, doc.MainDocumentPart.GetIdOfPart(imagePart)); } } // 摘抄自http://msdn.microsoft.com/EN-US/library/office/bb497430(v=office.15).aspx?cs-save-lang=1&cs-lang=csharp#code-snippet-5 private static void AddImageToBody(WordprocessingDocument wordDoc, string relationshipId) { // Define the reference of the image. var element = new Drawing( new DW.Inline( new DW.Extent() { Cx = 990000L, Cy = 792000L }, // 调节图片大小 new DW.EffectExtent() { LeftEdge = 0L, TopEdge = 0L, RightEdge = 0L, BottomEdge = 0L }, new DW.DocProperties() { Id = (UInt32Value)1U, Name = "Picture 1" }, new DW.NonVisualGraphicFrameDrawingProperties( new A.GraphicFrameLocks() { NoChangeAspect = true }), new A.Graphic( new A.GraphicData( new PIC.Picture( new PIC.NonVisualPictureProperties( new PIC.NonVisualDrawingProperties() { Id = (UInt32Value)0U, Name = "New Bitmap Image.jpg" }, new PIC.NonVisualPictureDrawingProperties()), new PIC.BlipFill( new A.Blip( new A.BlipExtensionList( new A.BlipExtension() { 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 = 990000L, Cy = 792000L }), //与上面的对准 new A.PresetGeometry( new A.AdjustValueList() ) { Preset = A.ShapeTypeValues.Rectangle })) ) { Uri = "http://schemas.openxmlformats.org/drawingml/2006/picture" }) ) { DistanceFromTop = (UInt32Value)0U, DistanceFromBottom = (UInt32Value)0U, DistanceFromLeft = (UInt32Value)0U, DistanceFromRight = (UInt32Value)0U, EditId = "50D07946" }); // Append the reference to body, the element should be in a Run. wordDoc.MainDocumentPart.Document.Body.AppendChild(new Paragraph(new Run(element))); } } }
本文示例运行效果如下图所示:
