首先新建一個(gè)名為article.aspx的文件,將以下內(nèi)容拷貝到article.aspx.cs中:

public partial class article : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        int cpage = Convert.ToInt32(Request.QueryString["page"]);
        if(cpage==0)
        {
            this.hlFrontPage.NavigateUrl = Request.ServerVariables["SCRIPT_NAME"];
            this.hlNextPage.NavigateUrl = Request.ServerVariables["SCRIPT_NAME"] + "?page=" + Convert.ToString(cpage + 2);
        }
        else
        {
            this.hlFrontPage.NavigateUrl = Request.ServerVariables["SCRIPT_NAME"] + "?page=" + Convert.ToString(cpage - 1);
            this.hlNextPage.NavigateUrl = Request.ServerVariables["SCRIPT_NAME"] + "?page=" + Convert.ToString(cpage + 1);
        }
        this.hlFirstPage.NavigateUrl = Request.ServerVariables["SCRIPT_NAME"];
             dataBin();
        //***************************************************
        //PageCount的值必須在數(shù)據(jù)綁定之后才能得到,否則只能是0
        //***************************************************
        int lastPage =this.DataGrid1.PageCount;//lastPage是記錄總頁(yè)數(shù)
        this.hlLastPage.NavigateUrl = Request.ServerVariables["SCRIPT_NAME"] + "?page="+Convert.ToInt32(lastPage);
        if (cpage ==Convert.ToInt32(this.DataGrid1.PageCount))
        {
            this.hlNextPage.NavigateUrl = Request.ServerVariables["SCRIPT_NAME"] + "?page=" + Convert.ToString(lastPage);
            this.hlFrontPage.NavigateUrl = Request.ServerVariables["SCRIPT_NAME"] + "?page=" + Convert.ToString(cpage - 1);
        }
        this.lbShowMess.Text= "當(dāng)前第"+Convert.ToInt32(this.DataGrid1.CurrentPageIndex+1)+"頁(yè)";
    }
    public void dataBin()
    {
        DB mydb = new DB();
        SqlConnection conn = mydb.createConn();
        conn.Open();
        SqlDataAdapter sdr = new SqlDataAdapter();
        DataSet ds = new DataSet();

        sdr.SelectCommand = new SqlCommand("select * from [User]", conn);
        sdr.Fill(ds, "users");

        int page=Convert.ToInt32(Request.QueryString["page"]);
        if (page == 0)
        {
            page = 1;
        }
        this.DataGrid1.CurrentPageIndex =Convert.ToInt32(page-1);
        this.DataGrid1.DataSource = ds.Tables["users"];
        this.DataGrid1.DataBind();
        conn.Close();
    }
    protected void DataGrid1_PageIndexChanged(object source, DataGridPageChangedEventArgs e)
    {

    }
}

再將以下內(nèi)容拷貝到article.aspx中

分享：解讀訪問本機(jī)IIS站點(diǎn)被要求輸入用戶名和密碼
訪問發(fā)布在本機(jī)IIS上的站點(diǎn)時(shí)，老彈出一個(gè)框要求輸入用戶名密碼，而輸入本機(jī)的管理員帳戶，卻還是彈出這個(gè)框來(lái)。這個(gè)問題非常煩，網(wǎng)上的意見如下： 1.設(shè)置發(fā)布目錄文件夾的訪問權(quán)限，允許everyone訪問。 2.設(shè)置IIS安全選項(xiàng)卡中，允許匿名訪問。這里漏過了一
