c# - 在 C# 中用同一位置的图像替换文本

Question

此代码用图像替换文本，但它放置图像的多个副本并将它们放在文档的开头。我希望将图像放置在与文本相同的位置。我的查找文本在表格单元格中可用。是因为这个吗？

        {

          void DocumentDigitalSign(string filep,string findt,string replacet);
        }

       public class Program : IMyClass
        {
             public void DocumentDigitalSign(string filep, string findt, string imagepath)
            {
                string filepath = filep;
                string Findtext = findt;
                word.Application app = new word.Application();
                word.Document doc = app.Documents.Open(filepath);

                word.Range myStoryRange = doc.Range();

                //First search the main document using the Selection
                word.Find myFind = myStoryRange.Find;
                myFind.Text = Findtext;               myFind.Replacement.Application.Selection.InlineShapes.AddPicture(imagepath);

                myFind.Execute(Replace: word.WdReplace.wdReplaceAll);

                //'Now search all other stories using Ranges
                foreach (word.Range otherStoryRange in doc.StoryRanges)
                {
                    if (otherStoryRange.StoryType != word.WdStoryType.wdMainTextStory)
                    {
                        word.Find myOtherFind = otherStoryRange.Find;
                        myOtherFind.Text = Findtext;          myOtherFind.Replacement.Application.Selection.InlineShapes.AddPicture(imagepath);
                        myOtherFind.Wrap = word.WdFindWrap.wdFindContinue;
                        myOtherFind.Execute(Replace: word.WdReplace.wdReplaceAll);
                    }

                    // 'Now search all next stories of other stories (doc.storyRanges dont seem to cascades in sub story)
                    word.Range nextStoryRange = otherStoryRange.NextStoryRange;
                    while (nextStoryRange != null)
                    {
                        word.Find myNextStoryFind = nextStoryRange.Find;
                        myNextStoryFind.Text = Findtext;
                        myNextStoryFind.Replacement.Application.Selection.InlineShapes.AddPicture(imagepath);
                        myNextStoryFind.Wrap = word.WdFindWrap.wdFindContinue;
                        myNextStoryFind.Execute(Replace: word.WdReplace.wdReplaceAll);

                        nextStoryRange = nextStoryRange.NextStoryRange;
                    }

                }
                app.Documents.Save();
                app.Documents.Close();
            }

        }

Replacement.Application 是对应用程序对象的引用。当您对其调用 AddPicture() 时，图片会在执行查找操作之前立即插入到当前位置。

我看到了两种可能性:

1. 加载图片，将其放入 Windows 剪贴板，然后执行查找操作，指定“^c”作为替换文本。 Word 会将“^c”替换为剪贴板的当前内容。这就是documentation说:

ReplaceWith
Type: System.Object
Optional Object.
The replacement text. To delete the text specified by the Find argument, use an empty string (""). You specify special characters and advanced search criteria just as you do for the Find argument. To specify a graphic object or other non-text item as the replacement, move the item to the Clipboard and specify "^c" for ReplaceWith.

1. 不要使用 wdReplaceAll，而是使用 wdReplaceNone，这样查找操作本身不做任何替换。但是您随后有机会在找到的位置插入您的内容。循环执行此操作，直到不再出现为止。
