4.5信息审核设计及实现
为了保证发布信息的安全性、完整性、可靠性，系统中设计了信息审核的模块，对信息的标题、内容进行审核，审核通过后才能对信息进行发布，工浏览者浏览、阅读以及评论。如图4.7所示。
 
图4.7 信息审核页面
点击“审核”进入审核界面，审核信息标题、内容后点击审核通过即可，如图4.8所示。

图4.8信息审核页面

此功能实现的关键代码如下：
public partial class Manage_News_checkdate : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            TextBox3.Text = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss");
            bind();
        }
    }
    private void bind()
    {
        string sSql = "select * from News where id="+Request["id"].ToString();
        SQL s = new SQL();
        DataView dv = s.DSSearch(sSql).Tables[0].DefaultView;
        TextBox1.Text = dv[0].Row["Title"].ToString();
        TextBox2.Text = dv[0].Row["Contents"].ToString();
    }
