如何动态地将图像分配给图像不在应用程序根目录上的图像按钮 [英] How do I dynamically assign images to image buttons where images are not on the application root

问题描述

大家好，

我试图在运行时将图像分配给图像按钮，但是当我运行我的应用程序时，我只得到x。如果我做了类似

 img_header.ImageUrl =〜/ images /& imagefilename& .jpg
 

但是，如果我尝试像

 img_header.ImageUrl =C：\ Files\Images\imagefilename.jpg
 

然后它不会在运行时加载图像。



当我在设计时设置ImageUrl时，它会在运行时显示图像。但是这对我不起作用，因为我需要在运行时根据不同的因素更改图像



任何帮助都将受到赞赏

Hi all,
I am trying to assign images during runtime to an image button but I am only getting "x" when i run my application. It works if i do something like

img_header.ImageUrl = "~/images/" & imagefilename & ".jpg"

However, if I try something like

img_header.ImageUrl = "C:\Files\Images\imagefilename.jpg"

then it doesn't load the image during runtime.

When I set the ImageUrl during design time, then it shows the image at runtime. but this doesn't work for me because i need to change the image during runtime based on different factors

Any help would be appreciated
