无法写入生产服务器上的web.config的AppSettings [英] Unable to write AppSettings of web.config on production server

问题描述

我已经写了下面的code来更改在web.config的AppSettings值，当我测试它在我的dev的机器，它工作正常。不过，我复制页面到生产服务器后，改变值不更新。

I've written following code to make changes to the values of AppSettings in the web.config and when I tested it on my dev machine, it works fine. However, after I've copied the page to the production server, changing the values are not updated.

Configuration myConfig = WebConfigurationManager.OpenWebConfiguration("~");
        try
        {
            myConfig.AppSettings.Settings["username"].Value = txtUsername.Text;
            myConfig.AppSettings.Settings["password"].Value = txtPassword.Text;
            myConfig.AppSettings.Settings["senderNum"].Value = txtSMSCenter.Text;
            myConfig.Save(ConfigurationSaveMode.Modified);
            ConfigurationManager.RefreshSection("appSettings");
            lblStatus.Text = "Config updated at: " + DateTime.Now.ToString();
        }
        catch (ConfigurationException ex)
        {
            lblStatus.Text = ex.Message;
        }

对于管理员

我已经允许进行写访问，网络服务和IIS_IUSRS到web.config中，但仍然无法正常工作。

I've allowed write access for Administrator, Network Service and IIS_IUSRS to web.config but still doesn't work.

有何意见？
