winform 替换word中指定内容



 需要引用两个dll：Interop.Microsoft.Office.Core.dll和Microsoft.Office.Interop.Word.dll （可以到我的资源里面去下载）

try

                    }));
                //定义替换方式对象
                object P_Replace = Microsoft.Office.Interop.Word.WdReplace.wdReplaceAll;
                //执行替换

                //保存文档
                G_WordApplication.Documents.Save(ref G_Missing, ref G_Missing);
                //关闭文档
                ((Microsoft.Office.Interop.Word._Document)P_Document).Close(ref G_Missing, ref G_Missing, ref G_Missing);
                //退出word应用程序
                ((Microsoft.Office.Interop.Word._Application)G_WordApplication).Quit(ref G_Missing, ref G_Missing, ref G_Missing);

            }
