Question

本人做程序时出现的问题，语言C#

详细代码如下
for (int i = 0; i <= 4; i++)
{
modelZiChan.nianFen = DateTime.Now.Year - i;
modelZiChan.zongZiChan = ((TextBox)FindControl("zongZiChan" + i)).Text;
modelZiChan.zongFuZhai = ((TextBox)FindControl("zongFuZhai" + i)).Text;
modelZiChan.fuZhaiLv = ((TextBox)FindControl("fuZhaiLv" + i)).Text;
modelZiChan.yeWuShouRu = ((TextBox)FindControl("yeWuShouRu" + i)).Text;
modelZiChan.jingLiRun = ((TextBox)FindControl("jingLiRun" + i)).Text;
modelZiChan.guDingZiChan = ((TextBox)FindControl("guDingZiChan" + i)).Text;
modelZiChan.liuDongZiChan = ((TextBox)FindControl("liuDongZiChan" + i)).Text;
modelZiChan.jingZiChan = ((TextBox)FindControl("jingZiChan" + i)).Text;
modelZiChan.xiangMuId = XiangMuID;
if (bllZiChan.Add(modelZiChan) > 0)
{ }
else
{
Response.Write("<script>alert('系统信息：企业资产添加出现错误，请查证重新添加企业资产！');location='AddXiangMu.aspx';</script>");
}
}
报错如下：
无法将类型为“System.Web.UI.HtmlControls.HtmlInputText”的对象强制转换为类型“System.Web.UI.WebControls.TextBox”。

Answer 1

类型转换错误，说明你其中有HtmlInputText控件，而它是不能被强转为TextBox类型的。

Answer 2

HtmlInputText是客户端控件，textbox是服务器控件。不能用强制转换来转换。把HtmlInputText换成textbox就ok了
