急。树型目录问题

Question

我在.cs中写了一个实现树型目录showTree()。
将生成的html代码赋给了一个变量strTree
怎样才能在.aspx页面中显示该目录。

Answer 1

看不懂什么意思.
Lable1.Text = strTree ; ?

Answer 2

变量定义为 public 访问级别
aspx中写
在页面里写  <%=变量名%>或者在页面里放一个label控件
cs 中写
label1.Text = 变量名；

Answer 3

label1.Text = 变量名；
我试过，好象不能显示图片吧<%=变量名%>也是一片空白

Answer 4

public string strTree;
...
...
<%=strTree%>

Answer 6

大家帮我看一下，上面代码中的返回值strTree，怎样才能在.aspx中实现出来

Answer 7

我用的是vb.net   你试试
Page_Load 里加
response.write(strTree)

Answer 8

也不行啊，我本来是直接用response.write写的，后来才改成用变量存放
