C#Word文档 - 如何清除格式?

标签: c# replace formatting ms-word

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颜色(保持表格单元格背景颜色不变),并删除word文档中带删除线的所有文本,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。

下面是一个从谷歌中可用的随机示例中拼凑出来的大型示例,展示了如何将特定类型的格式应用于使用Find.Execute()找到的随机字符串。然而,我不知道如何只做如上所述。

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;
    }

感谢您的帮助!而且我的意思是任何一种,只要开始研究如何发现格式就会有很大帮助,我想。 :)

这不是C#特定的问题;这是一个Word对象模型问题(我推荐你herehere)。

关于您的具体问题,我建议您在Word中打开宏记录器,执行操作,并查看生成的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:

  • 为清晰起见,请使用using语句。而不是Microsoft.Office.Interop.Word._Application word,而是在文件顶部添加using Microsoft.Office.Interop.Word,然后您就可以只写_Application word
  • 如果您只需要文件夹名称,请使用静态Path.GetDirectoryName方法并保存为string变量,而不是创建FileInfo对象
  • 从.NET 4开始,您可以在调用Documents.OpenDocument.SaveAsDocument.Close时跳过可选参数。这也意味着您不需要object missing
  • 用户真的不需要看到任何内容,因此无需调用Document.Activate
  • 重用Word.Application实例可能更好,而不是为每次调用重新创建它。
