如何从隐藏字段向数组列表中插入多个值 [英] How to insert multiple values from hidden field to array list

问题描述

删除了dupelicate



i hava此字段中的多个值

i需要插入值列表



我尝试过的事情：

removed dupelicate

i hava multiple value in this field
i need to inset the values to list

What I have tried:

foreach (TreeNode node in TRVPersonnel.CheckedNodes)
{

	hftreenodevalue.Value += node.Value + ",";

   Session["idRole"] = hftreenodevalue.Value;
	list = Session["idRole"] as List<string>;

	foreach (var L in list)
	{
	}
}

推荐答案

因为你要存储以逗号分隔格式的数据，你应该用逗号分割得到字符串数组/列表

Since you are storing the data in comma separated format, you should split by comma to get the string array/list

string csv = Convert.ToString(Session["idRole"]);
           List<string> list = csv.Split(',').ToList();
