Question

我有一个替换文档特定文本中的标记的方法。如何更换标签图片？

Answer 1

这是一段代码，用于在表格中查找文本为“PersonMainPhoto”的单元格。清除表格单元格并插入图像。希望这可以指导您朝着正确的方向发展。

插入图像分为两部分：

将图像部分添加到文档
在正文文本中插入对图像的引用 - 包含有关缩放，定位等的各种细节。

插入引用的代码来自精彩的OpenXML SDK文档：https://msdn.microsoft.com/en-us/library/office/bb497430.aspx

图片如何适合表格单元格？？

不修复它。 Cx = 990000L，Cy = 792000L

像这样吗？

   TableCellProperties tableCellProperties1 = VARIABLE.GetFirstChild<TableCellProperties>();

   TableCellWidth tableCellWidth1 = tableCellProperties1.GetFirstChild<TableCellWidth>();

   int _width = Int32.Parse(tableCellWidth1.Width);

   TableRowProperties tableRowProperties1 = 

   VARIABLE.Parent.GetFirstChild<TableRowProperties>();

   TableRowHeight tableRowHeight1 = 

   tableRowProperties1.GetFirstChild<TableRowHeight>();
   int _height = Int32.Parse(tableRowHeight1.Val);     

   document.MainDocumentPart.Document.Save();

C＃WordprocessingDocument - 在单元格中插入图像
