Question

I have an .aspx page that I’m trying to render, but when I go to render characters, I get strange results.

<%= default(char) %>

Expands to the following in FF and Chrome, but not in IE:

�

Is there a way to ignore the value if it’s the null character? I’ve tried default(char).ToString(), but it seems have the same result. When there’s a null character, I just want to ignore it.

Answer 1

The default value for char is \0 or which is the equivalent of null but not actually a System.Null value, so the behaviour is as expected.

If you want to avoid that test for:

<%= mychar != '\0' ? mychar : '' %>

It’s important to remember to use single quotes for chars.

My worry is that this is a long way around doing this; what are you actually trying to do in your main code ?

Edit: To give a code sample to the fix paraphrased in my comment:

<%= myobj.charProp == '\0' ? "''" : myobj.charProp.ToString() %>
