asp.net 如何用input type=file 上传图片？
<input size=10 type=File name=cPub"+allCount+">

怎样获取file的路径上传到数据库？

因为是用javascript动态新增行的，所以只能用file 不能用asp.net中的控件fileupload。

老兄,这个已经是老生常谈了:
1.如果你页面中没有服务端upload控件,请在Page_Load中注册form的enctype(如果有服务端upload控件,会自动注册的)
protected void Page_Load(object sender, EventArgs e)
{
this.form1.Enctype = "multipart/form-data";
}
2.上传文件的代码
protected void Button1_Click(object sender, EventArgs e)
{
//核心是使用Request.Files方法
for (int i = 0; i < Request.Files.Count; i++)
{
Request.Files[i].SaveAs(Server.MapPath("***"));
}
}
