我在此代码中遇到了一些错误

Dear All Experts,
I got some errors in this code

		l = (Label)v.FindControl("Label2");
		l.Text = dt.Rows[ctr]["question"];

感谢您的宝贵重放.

推荐答案

您能告诉您您遇到了什么错误吗?
首先检查您是否没有为数组提到名称，而是简单地添加了新名称，
修改为:

can u tell what error you are having ?
first check that u didn''t mentioned name for the array instead simply u added new,
edit it as:

int[] a=new int[array_size];

您没有将Session["Answered"]强制转换为适当的type，也没有检查是否为null使用之前

You are not casting your Session["Answered"] to the appropriate type or checking if it is null or not before using it
