passing html string to stringbuilder does not work

Question

I am writing html tags in a an html file by following code in C#:

StringBuilder sbMarquee = new StringBuilder();
sbMarquee.Append("<a href= #  onclick = showimage('Images\\\\Code00005_0001.jpg')>").Append("<img src=Images\\\\thumbnails\\\\Code00005_0001.jpg></img>").Append("</a>");
_hdCaseMarquee.InnerHtml = sbMarquee.ToString();

But, I get following HTML output:

<a href="#" onclick="showimage('Images\\Code00005_0001.jpg')"><img src="Images\\thumbnails\\Code00005_0001.jpg"></a></marquee>

Following tag from the string is completely ignored:

</img>

Please Help

Try by properly quoting, e.g. Append("<img src=""Images\\\\thumbnails\\\\Code00005_0001.jpg""></img>"). — CodeCaster

Always check the contents of your variables in a debugger if you get results you don't expect. If you had, you'd have seen that sbMarquee.ToString() had exactly what you were expecting. — Bobson

@CodeCaster - ' and " are interchangeable for HTML, to the best of my knowledge, so long as you're consistent for each usage. — Bobson

@Bobson but now it says href= # and src={source} without quotes entirely. Anyway see spender's answer. — CodeCaster

@CodeCaster - Huh, good point. I'd missed that, since the output looked right for that part of it. — Bobson

I assume that you're looking at the HTML from the browser, in which case there's a strong likelihood that the closing tag of the img gets gobbled by the HTML parser for the following reason:

img

Tag omission Must have a start tag and must not have an end tag.

img tags do not require a closing tag in html (but the will require it if using xhtml)
