19.GridView数据导入Excel/Excel数据读入GridView
效果图：
解决方案：
页面增加一个按钮，单击事件添加如下方法：
protected void Button1_Click(object sender, EventArgs e) { Export("application/ms-excel", "学生成绩报表.xls"); } private void Export(string FileType, string FileName) { Response.Charset = "GB2312"; Response.ContentEncoding = System.Text.Encoding.UTF7; Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(FileName, Encoding.UTF8).ToString()); Response.ContentType = FileType; this.EnableViewState = false; StringWriter tw = new StringWriter(); HtmlTextWriter hw = new HtmlTextWriter(tw); GridView1.RenderControl(hw); Response.Write(tw.ToString()); Response.End(); } //如果没有下面方法会报错类型“GridView”的控件“GridView1”必须放在具有 runat=server 的窗体标记内 public override void VerifyRenderingInServerForm(Control control) { }
还有由于是文件操作所以要引入名称空间IO和Text
后台代码：
using System; using System.Data; using System.Configuration; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; using System.Data.SqlClient; using System.Drawing; using System.IO; using System.Text; public partial class Default7 : System.Web.UI.Page { SqlConnection sqlcon; SqlCommand sqlcom; string strCon = "Data Source=(local);Database=北风贸易;Uid=sa;Pwd=sa"; protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { bind(); } } public void bind() { string sqlstr = "select top 5 * from 飞狐工作室"; sqlcon = new SqlConnection(strCon); SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon); DataSet myds = new DataSet(); sqlcon.Open(); myda.Fill(myds, "飞狐工作室"); GridView1.DataSource = myds; GridView1.DataKeyNames = new string[] { "身份证号码" }; GridView1.DataBind(); sqlcon.Close(); } protected void Button1_Click(object sender, EventArgs e) { Export("application/ms-excel", "学生成绩报表.xls"); } private void Export(string FileType, string FileName) { Response.Charset = "GB2312"; Response.ContentEncoding = System.Text.Encoding.UTF7; Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(FileName, Encoding.UTF8).ToString()); Response.ContentType = FileType; this.EnableViewState = false; StringWriter tw = new StringWriter(); HtmlTextWriter hw = new HtmlTextWriter(tw); GridView1.RenderControl(hw); Response.Write(tw.ToString()); Response.End(); } public override void VerifyRenderingInServerForm(Control control) { } }
前台：
<asp:GridView runat="server" CellPadding="3" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" Font-Size="12px" > <FooterStyle BackColor="White" ForeColor="#000066" /> <Columns> <asp:BoundField DataField="身份证号码" HeaderText="编号" ReadOnly="True" /> <asp:BoundField DataField="姓名" HeaderText="姓名" /> <asp:BoundField DataField="出生日期" HeaderText="邮政编码" /> <asp:BoundField DataField="家庭住址" HeaderText="家庭住址" /> <asp:BoundField DataField="邮政编码" HeaderText="邮政编码" /> <asp:BoundField DataField="起薪" HeaderText="起薪" /> </Columns> <RowStyle ForeColor="#000066" /> <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" /> <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" CssClass="ms-formlabel DataGridFixedHeader"/> <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" /> </asp:GridView> <asp:Button runat="server" Text="导出" />
