Session问题

[taylermail]

Response.Write(Session["user"]);
if (Session["user"] == "A01")
{
dayin.Attributes.Add("style", "display:"); }
else
{
dayin.Attributes.Add("style", "display:none"); }
页面执行结果显示 Response.Write(Session["user"]);
为"A01"但还是执行语句else后面的？

可能有空格在里面 你trim下

[taylermail]

if (Session["user"].Tostring().Trim() == "A01") 这样用要出错

[hn86544951]

先判断不为空 之后 再trim 用3目运算

[taylermail]

if (Session["user"] != null&& Session["user"].ToString() != "") { if (Session["user"].Tostring().Trim() == "A01") { dayin.Attributes.Add("style", "display:"); } else { dayin.Attributes.Add("style", "display:none"); } } else { dayin.Attributes.Add("style", "display:none"); } 还是有问题哈

你把 session 值 付给一个变量看看到底是什么值

[taylermail]

Response.Write(Session["usercode"]); 我这样写一句 页面显示A01

[hn86544951]

if (Session["user"] != null && !string.IsNullOrEmpty(Session["user"].ToString()) && Session["user"].ToString().Trim() == "A01") { dayin.Attributes.Add("style", "display:"); } else { dayin.Attributes.Add("style", "display:none"); }

Session["user"]返回object类型要转换成string 应该是Session["user"].ToString()=="A01"
