You forgot to enclose the URL between quotes.
A better solution would be:

C#

Str.Append("<img src='" + url + "' visible='true' runat='server' style='width: 75px; height: 41px' />");

or

C#

Str.AppendFormat("<img src='{0}' visible='true' runat='server' style='width: 75px; height: 41px' />", url);

Kindly note the use of the single quotes inside the double-quotes-delimited-string.

thanks for reply.
i try with these two but same result image is not displayed

Solution 2

Check the source of the page to make sure the <img> tag is there, check the network tools to see if the browser has attempted to download the image. If it has and the result is 404 then your url path is wrong. Try using an absolute path rather than a relative one;

url = "/img/myimage.png";

Finally there is no point adding runat=server as that won't work for html you are injecting into the response stream as plain-text.

You haven't supplied enough code to be able to give specific help. View the source of the page and find your tag. Work out what is wrong with it and fix it. If the tag doesn't appear at all you need to look at the code that adds it, if it appears but is malformed you need to fix the code that renders the tag. If the tag is fine but the url is wrong you need to use the right url. We can't access your machine or run your code in context.

Solution 4

Str.Append("");
string imgurl = "~/img/images.png";
Str.AppendFormat("

", ResolveUrl(imgurl));
Str.Append("");
