asp.net GridView绑定到数组，用数组绑定到GridView

前台: 

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" AllowSorting="true">
    <Columns>
        <asp:BoundField DataField="id12333" HeaderText="id"/>
    </Columns>
</asp:GridView>

后台： 

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        BindGridView();
    }
}
void BindGridView()
{
    this.GridView1.DataSource = GetTable();
    this.GridView1.DataBind();
}
DataTable GetTable()
{
    DataTable dt = new DataTable();
    dt.Columns.Add("id12333", typeof(string));
    string[] str = new string[3];//把这个数组改成你的就好了
    str[0] = "11111111";
    str[1] = "2222";
    str[2] = "3333";
    for (int i = 0; i < str.Length; i++)
    {
        str[i] = str[i].ToString();
    }
    for (int j = 0; j < str.Length; j++)
    {
        DataRow row = dt.NewRow();
        row["id12333"] = str[j];
        dt.Rows.Add(row);
    }
    return dt;
}

下边的例子是从数据库里取出值，把值用split分割后在转成数组的形式绑定到GridView 
前台 

<asp:GridView ID = "gvwQXLB"  AutoGenerateColumns = "False" Width = "100%" runat = "server" Height="100%">
    <Columns>
        <asp:TemplateField HeaderText="选择">
            <ItemTemplate>
                <asp:CheckBox ID="ckbYHQX" runat="server"  />
            </ItemTemplate>
        </asp:TemplateField>

        <asp:BoundField DataField="bodfViewYHQX_menucaption" HeaderText="用户权限"/>

        <asp:BoundField DataField="bodfViewQXLB_qxlb" HeaderText="权限类别"/>

    </Columns>
</asp:GridView>

后台 

#region GridView绑定数据，显示用户权限

/// <summary>
/// GridView绑定数据，显示用户权限

private void gvwBind()
{
    DataSet ds = new DataSet();
    DataTable dt = new DataTable();
    dt.Columns.Add("bodfViewYHQX_menucaption", typeof(string));
    dt.Columns.Add("bodfViewQXLB_qxlb", typeof(string));

    Model.userInfo.UserKey modelQXFP = new Model.userInfo.UserKey();
    BLL.userInfo.UserKey bllQXFP = new BLL.userInfo.UserKey();

    string yhmc;
    yhmc = Request.QueryString["yhmc"];

    ds = (DataSet)bllQXFP.get_YHQXXX(yhmc);

    string[] bodfViewYHQX_menucaption = new string[ds.Tables["dzjc.dzjc_yhqx"].Rows.Count];//开辟数组空间
    string[] bodfViewQXLB_qxlb = new string[ds.Tables["dzjc.dzjc_yhqx"].Rows.Count];
for (int i = 0; i < ds.Tables["dzjc.dzjc_yhqx"].Rows.Count; i++)
    {
        bodfViewYHQX_menucaption = bllQXFP.get_YHQXXX(yhmc).Tables["dzjc.dzjc_yhqx"].Rows[i]["MENUCAPTION"].ToString().Split(',');//MENUCAPTION中数据格式个，“aa,bb,ccc,d,eeee,”
        bodfViewQXLB_qxlb[i] = Convert.ToString(bllQXFP.get_YHQXXX(yhmc).Tables["dzjc.dzjc_yhqx"].Rows[i]["qxlb"]);
    }

    for (int j = 0; j < bodfViewYHQX_menucaption.Length - 1; j++)//获得bodfViewYHQX_menucaption数组长度减一，因为MENUCAPTION中数据存储格式为“aa,bb,ccc,d,eeee,”，最后一个字符为“,”，所以要给长度减一
    {
        DataRow row = dt.NewRow();
        row["bodfViewYHQX_menucaption"] = bodfViewYHQX_menucaption[j];//把分割出来放到数组里的字符串放到DataRow里
        row["bodfViewQXLB_qxlb"] = bodfViewQXLB_qxlb[0];//同一个用户的权限类别相同，所以取下标为0的数组
        dt.Rows.Add(row);
    }

    gvwQXLB.DataSource = dt;//绑定到数组
    gvwQXLB.DataBind();
    ds.Dispose();
}
