操作word之前需要在COM引入Microsoft Office 12.0 Object Library（文件库可能不一样）

然后添加using Microsoft.Office.Interop.Word;

读操作，docFilename为文件路径

private string Doc2Text(string docFileName)        
         {

            StringBuilder sb = new StringBuilder();

            ApplicationClass wordApp = new ApplicationClass();

            object fileobj = docFileName;

            object unknow = System.Reflection.Missing.Value;

            //打开指定文件

            try

            {

                _Document doc = wordApp.Documents.Open(ref fileobj, ref unknow, ref unknow,

                                  ref unknow, ref unknow, ref unknow,

                                  ref unknow, ref unknow, ref unknow,

                                  ref unknow, ref unknow, ref unknow,

                                  ref unknow, ref unknow, ref unknow, ref unknow

           );

                int paragraphsCount = doc.Paragraphs.Count;

                for (int i = ; i <= paragraphsCount; i++)

                {

                    sb.AppendLine(doc.Paragraphs[i].Range.Text.Trim());//获得文档内容

                }

                doc.Close(ref unknow, ref unknow, ref unknow);

                wordApp.Documents.Save(ref unknow, ref unknow);

                wordApp.Quit(ref unknow, ref unknow, ref unknow);

            }

            catch (Exception) { }

            return sb.ToString();

        }

写操作

 private Boolean WriteLocalFile(string DocFileName, string text)

        {

            try

            {

                object fileobj = DocFileName;

                object unknow = System.Reflection.Missing.Value;

                //打开word程序，创建一个新的word文档，但是还没有保存到硬盘中

                ApplicationClass wordApp = new ApplicationClass();

                _Document doc = wordApp.Documents.Add(ref unknow, ref unknow, ref unknow, ref unknow);

                doc.Content.Text += text;

                //保存word文档

                doc.SaveAs(ref fileobj, ref unknow, ref unknow, ref unknow, ref unknow, ref unknow, ref unknow, ref unknow, ref unknow, ref unknow, ref  unknow, ref unknow, ref  unknow, ref unknow, ref unknow, ref unknow);

                doc.Close(ref unknow, ref unknow, ref unknow);

                wordApp.Documents.Save(ref unknow, ref unknow);

                wordApp.Quit(ref unknow, ref unknow, ref unknow);

                return true;

            }

            catch (Exception) { return false; }

        }
