Regular expression in asp.net
-
Hi I need a regular expression for 1.00E+05.. I am using [-+]?[0-9]*\.?[0-9]+([eE][-+]?[0-9]+)?|^$ but it is not working..its accepts any character after the numeric value i.e. its returns true for 100abcd, however this is wrong. Only a single e or E should accept.

Try: [-+]?([0-9]+)\.([0-9])+[eE][\+-]?[0-9][0-9]? I strongly recommend you get a copy of Expresso[^] - it makes working with regexes so much easier... [edit]eh up - one o me brackets vanished...it's back now![/edit]

Thanks for your help..but I need to allow blank also, means either there should be blank or valid value, but this expression does not allow blank, that's why I added |^$ at the end of the expression. But still not working properly. :((
