C#Word文档-如何清除格式

本文关键字:清除 格式 何清除 文档 C#Word | 更新日期: 2023-09-27 18:00:12

困境相当简单。我需要创建一个小应用程序,它将清除所有字体背景色(保持表格单元格背景色不变),并删除word文档中所有带删除线的文本,然后将文档保存到另一个文件夹中。否则,文档的格式应保持不变。

下面是一个从谷歌上的随机示例中拼凑而成的大示例,展示了如何将特定类型的格式应用于使用Find找到的随机字符串。执行()。然而,我不知道如何只做上面描述的事情。

public static string searchDoc(string fileNameRef)
    {
        Microsoft.Office.Interop.Word._Application word = new Microsoft.Office.Interop.Word.Application(); ;
        Microsoft.Office.Interop.Word._Document doc = new Microsoft.Office.Interop.Word.Document();
        object missing = System.Type.Missing;
        try
        {
            System.IO.FileInfo ExecutableFileInfo =
                    new System.IO.FileInfo(System.Reflection.Assembly.GetEntryAssembly().Location);
            object fileName =
                System.IO.Path.Combine(ExecutableFileInfo.DirectoryName, fileNameRef);
            doc = word.Documents.Open(ref fileName, ref missing, ref missing, ref missing
                , ref missing, ref missing, ref missing, ref missing, ref missing, ref missing
                , ref missing, ref missing, ref missing, ref missing, ref missing, ref missing);
            doc.Activate();
            //object findStr = "hello"; //sonething to find
            // THIS is the part where I fail, I can't find of a way to Find.Execute on formatting
            // as opposed to mere strings.
            //while (word.Selection.Find.Execute(ref findStr))  //found...
            //{
            //    //change font and format of matched words
            //    word.Selection.Font.Name = "Tahoma"; //change font to Tahoma
            //    word.Selection.Font.ColorIndex = Microsoft.Office.Interop.Word.WdColorIndex.wdRed;  //change color to red
            //}
            object saveFileName = ExecutableFileInfo.DirectoryName + "''New''" + fileNameRef;
            doc.SaveAs(ref saveFileName, ref missing, ref missing, ref missing, ref missing
                , ref missing, ref missing, ref missing, ref missing, ref missing, ref missing
                , ref missing, ref missing, ref missing, ref missing, ref missing);
        }
        catch (Exception)
        {
        }
        finally
        {
            doc.Close(ref missing, ref missing, ref missing);
            word.Application.Quit(ref missing, ref missing, ref missing);
        }
        return fileNameRef;
    }

谢谢你的帮助!我的意思是,我想,只要开始学习如何识别格式就会有很大帮助。:)

C#Word文档-如何清除格式

这不是一个C#特有的问题;这是一个单词对象模型问题(我指的是这里和这里)。

至于您的具体问题,我建议您打开Word中的宏记录器,执行操作,然后查看生成的VBA代码。然后你可以在C#中应用它。

试试这个:

using System;
using Microsoft.Office.Interop.Word;
using System.IO;
using System.Reflection;
namespace WordFormattingFindReplace {
    class Program {
        static void Main(string[] args) {
        }
        public static string searchDoc(string fileName) {
            _Application word = new Application(); ;
            _Document doc;
            string folderName = Path.GetDirectoryName(Assembly.GetEntryAssembly().Location);
            string filePath = Path.Combine(folderName,fileName);
            doc = word.Documents.Open(filePath);
            var find=doc.Range().Find;
            find.Text="Hello";
            find.Format=true;
            find.Replacement.Font.Name="Tahoma";
            find.Replacement.Font.ColorIndex=WdColorIndex.wdRed;
            find.Execute(Replace:WdReplace.wdReplaceAll);
            doc.SaveAs2(Path.Combine(folderName,"New",fileName));
            doc.Close();
            //We need to cast this to _Application to resolve which Quit method is being called
            ((_Application)word.Application).Quit();
            return fileName;
        }
    }
}

一些注意事项:

  • 为了清楚起见,请使用using语句。在文件的顶部添加using Microsoft.Office.Interop.Word而不是Microsoft.Office.Interop.Word._Application word,然后就可以只写_Application word
  • 如果只需要文件夹名称,请使用静态Path.GetDirectoryName方法并另存为string变量,而不是创建FileInfo对象
  • 截至。NET 4时,可以在调用Documents.OpenDocument.SaveAsDocument.Close时跳过可选参数。这也意味着您不需要object missing
  • 这里没有用户真正需要看到的内容,因此不需要调用Document.Activate
  • 重用Word.Application实例可能更好,而不是为每个调用重新创建它
