一个简单的问题：将字符串转换为c＃asp.net mvc中的图像标签

Question

I used a generic image handler to handle image

<td width="100px"><%:MyImageHandler.CreateImage(item.PictureId, 100).ToString()%></td>  

and the generic handler should return a string like

<img src='/Photo/MyImageHandler.ashx?id=9&size=100'/>

I am exhausted to output a string in the form of a image tag
I tried the string builder and other string constructor and it only return :

<img src='/Photo/MyImageHandler.ashx?id=9&size=100'/>

rather than
<img src='/Photo/MyImageHandler.ashx?id=9&size=100'/>

Do you have any suggestions on that? I really need your help.

Answer 1

: will automatically encode your string which is why your < is getting turned into a <

You have 2 options

1. return a MvcHtmlString instead of a string in the method createImage
2. use <%= instead of <%:

You would use an MvcHtmlString if you want to return raw HTML from an MVC helper method.
