可以找word文档里面的文本,但不懂如何替换,
用一个str替换掉'测试'

if (wDoc.Content.Text.IndexOf("测试") > 0)
            {wDoc.Content.Text.Replace("测试",str);
       
                           }

Answer 3

word替换字符串后，样式都变了
Microsoft.Office.Interop.Word.ApplicationClass app =new Microsoft.Office.Interop.Word.ApplicationClass();
//Microsoft.Office.Interop.Word.Application  app = new Microsoft.Office.Interop.Word.a();
object nullobj = System.Reflection.Missing.Value;
object file = filePath;
Microsoft.Office.Interop.Word.Document doc = app.Documents.Open(
ref file, ref nullobj, ref nullobj,
ref nullobj, ref nullobj, ref nullobj,
ref nullobj, ref nullobj, ref nullobj,
ref nullobj, ref nullobj, ref nullobj,
ref nullobj, ref nullobj, ref nullobj, ref nullobj);
 
doc.Content.Text = doc.Content.Text.Replace(strOld, strNew);  
// doc.Content.AutoFormat();
// Microsoft.Office.Interop.Word.Range range = null;
doc.Close(ref nullobj, ref nullobj, ref nullobj);
app.Quit(ref nullobj, ref nullobj, ref nullobj);

Answer 4

wDoc.Content.Find.Execute(ref tempss, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref shuju, ref missing, ref missing, ref missing, ref missing, ref missing);
