<％=％>和<％＃％>之间有什么区别
[英]What is difference between <%=%> and <%#%>
问题描述
All, As for the inline expression in asp.net ,I had some questions about them. 
全部，至于asp.net中的内联表达式，我对它们有一些疑问。
- What is the difference between them ? 他们之间有什么区别？
- In what situation ,Which one is better? 在什么情况下，哪一个更好？
By the way, I found below code the first one doesn't works , but second one works. 顺便说一下，我发现下面的代码第一个不起作用，但第二个起作用。 Why? 为什么？
<head runat="server">
<title></title>
<script src="<%#FullyQualifiedApplicationPath%>Scripts/jquery.js" type="text/javascript"></script>
</head><!--Not OK-->
<head runat="server">
<title></title>
<script src="<%=FullyQualifiedApplicationPath%>Scripts/jquery.js" type="text/javascript"></script>
</head><!--OK-->
FullyQualifiedApplicationPath is a variable defined in code behind. FullyQualifiedApplicationPath是在代码后面定义的变量。 Thanks your review. 谢谢你的评论。

<%#%> is used to bind some data or control by using BIND(read and write purpose) or EVAL(for readonly purpose). <％＃％>用于通过使用BIND（读写目的）或EVAL（用于只读目的）来绑定某些数据或控件。
Where as <%=%> is used to display the value of a session in a html page. 其中<％=％>用于在html页面中显示会话的值。

For example when u w3ant to bind data to a grid we use the following syntax 例如，当您想要将数据绑定到网格时，我们使用以下语法
<ItemTemplate>
<asp:Label ID="lbl_Id" Text='<%# Bind("Id") %>' runat="server"></asp:Label>
</ItemTemplate>
The above syntax is used to bind the data in the gridview 上述语法用于绑定gridview中的数据
while the <%=%> You will be able to do c# coding in default. 而<％=％>你可以在默认情况下进行c＃编码。 aspx page as well, here is the sample code. aspx页面也是，这里是示例代码。
To show some output on the page and do some coding over out there
<%=Session["value"].ToString() %>
It will load the session value in the default page. 它将在默认页面中加载会话值。
