N久么发过贴，冒个泡，发个代码，不妥之处请指正！
参考了高手用VB6.0写的using System;
using System.Collections.Generic;

        /// <returns></returns>

}以下是使用        private void btnGetOfficePath_Click(object sender, EventArgs e)

            try

            }
            catch (Exception ex)
            {
                MessageBox.Show("无法获取系统Office信息");
            }
            if (!string.IsNullOrEmpty(officePath) && !string.IsNullOrEmpty(officeVersion))
            {
                MessageBox.Show(string.Format("版本:{0}\r\n安装路径:{1}",officeVersion,officePath));
            }
        }        //是否安装及版本
        private void btnIsInstall_Click(object sender, EventArgs e)
        {
            try
            {
                string version = "";
                if (OfficeOperator.IsInstall(out version))
                {
                    MessageBox.Show(string.Format("当前安装了{0}", version));
                }
                else
                {

                }
            }
            catch(Exception ex)
