通过C#打开word文件

 //打开指定word文件（实现）
            object missing = Type.Missing;
            object fileName = Application.StartupPath + "\\document\\vs打包安装与部署(含图).doc";//这里要求文件放在bin的debug中，文件夹名为document（举例）

            Microsoft.Office.Interop.Word.Application word = new Microsoft.Office.Interop.Word.Application();
            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);
            word.Visible = true;

要注意先在解决方案中添加word的组件引用。方法是在解决方案的“引用”上右击，添加，com组件，选择Microsoft.Office.Interop.Word组件即可。
