页面后台CS代码:
void BindFilesList()
{
string strSql = "select Name from tableC";
DataTable dt = m_db.ExecuteDataTable(strSql);
GridView1.DataSource = dt;
GridView1.DataBind();
}
protected void PackDown_Click(object sender, EventArgs e)
{
Response.Clear();
Response.ContentType = "application/zip";
Response.AddHeader("content-disposition", "filename=DotNetZip.zip");
using (ZipFile zip = new ZipFile(System.Text.Encoding.Default))
{
foreach (GridViewRow gvr in GridView1.Rows)
{
if (((CheckBox)gvr.Cells[0].Controls[1]).Checked)
{
zip.AddFile(Server.MapPath("SoftwareDownload/") + (gvr.Cells[1].Controls[1] as Label).Text, "");
}
}
zip.Save(Response.OutputStream);
}
Response.End();
}
重点参考后台CS里的PackDown_Click方法
