    方法一:

    异常判断法(根据返回结果形式)

    // 使用地方
    private void buttonOk_Click(object sender, EventArgs e)
    {
       if (codeboolisExcelInstalled())
       {
        MessageBox.Show("本机已安装Excel文件");
       }
       else
       {
        MessageBox.Show("当前系统没有发现可执行的Excel文件, 如需使用Excel功能请先安装office 2003", "警告", MessageBoxButtons.OK, MessageBoxIcon.Warning);
       }
    }

    //判断本机是否安装Excel文件方法
    private bool codeboolisExcelInstalled()
    {
        Type type = Type.GetTypeFromProgID("Excel.Application");
        return type != null;
    }

    ====================================================================

    方法二:

    注册表检查发

    判断注册表里有没有SOFTWARE\\Microsoft\\Office\\12.0\\Word\\InstallRoot\\Excel.exe 其中12.0 11.0需要同时判断,因为11.0是office 2003 12.0是office 2007

    // 使用地方
    private void buttonOk_Click(object sender, EventArgs e)
    {
       if (ExistsRegedit())
       {
        MessageBox.Show("本机已安装Excel文件");
       }
       else
       {
        MessageBox.Show("当前系统没有发现可执行的Excel文件, 如需使用Excel功能请先安装office 2003", "警告", MessageBoxButtons.OK, MessageBoxIcon.Warning);
       }
    }

    /// <summary>
    /// Self_Variable:查询注册表某个键值是否存在
    /// </summary>
    /// <returns></returns>
    public bool ExistsRegedit()
    {
        bool ifused = false;
       RegistryKey rk = Registry.LocalMachine;
        RegistryKey akey = rk.OpenSubKey(@"SOFTWARE\\Microsoft\\Office\\11.0\\Word\\InstallRoot\\");
        RegistryKey akeytwo = rk.OpenSubKey(@"SOFTWARE\\Microsoft\\Office\\12.0\\Word\\InstallRoot\\");
        //检查本机是否安装Office2003
        if (akey != null)
        {
            string file03 = akey.GetValue("Path").ToString();
            if (File.Exists(file03 + "Excel.exe"))
            {
                ifused = true;
             }
         }
         //检查本机是否安装Office2007
         if (akeytwo != null)
         {
              string file07 = akeytwo.GetValue("Path").ToString();
              if (File.Exists(file07 + "Excel.exe"))
              {
                  ifused = true;
               }
          }
              return ifused;
    }

    =======================================

    string strInstallPath = file03 /file07 + "Excel.exe";

    //获取Excel进程信息
    System.Diagnostics.ProcessStartInfo psInfo = new   System.Diagnostics.ProcessStartInfo(strInstallPath);

    //运行Excel
    System.Diagnostics.Process.Start(strInstallPath);
