Comparing two Chars?

I am trying to compare two characters. I can watch the charTemp array fill up and when it gets to the character I am comparing it to, it just bypasses it as if they are not equal. The code is as follows. Am I comparing them incorrectly? Do I need to compare the decimal value or something?

EDIT: This ((char)tr.Read() == '&') which is right above it works fine. And I have initialized the char array as:

char[] charTemp = new char[50];

while (charTemp[i] != '%')
{
charTemp[i] = (char)tr.Read();
i++;
}

Thanks
