如何在ASP.NET中将Request.QueryString [“”]绑定到Eval（）

Question

ImageUrl='<%#Eval("Name","../Master Pages/DisasterImages/") %>'+'<%#Eval("Request.QueryString["DisID"].ToString()/{0}") %>'

DisID is a folder name.

What I want is to display the images in the directory. I have done it using a repeater control. The problem is now I want to get the folder name in the QueryString. How can I do this? Above is the code I have tried without achieving the desired outcome...

Any help would appreciated.

Thank you!

Answer 1

use <%= instead of <%#. Example:

<%= Request.QueryString["DisID"] %>

I have noticed another issue with your code, you need to be careful when using quotes inside a string. You need to escape them. Therefore

"Request.QueryString["DisID"].ToString()/{0}"

should look like this

"Request.QueryString[\"DisID\"].ToString()/{0}"

Notice the backslash that serves for escaping characters.
