c# error in regular expression

Question

I am trying to find a regular expression where the input is just arabic, space and numbers (but with no predefined order)

Regex regex = new Regex("[\u0600-\06ff\\s0-9]*");

when the input is 4, this is the exception:

parsing "[؀-

{"parsing \"[؀-\06ff\\s0-9]*\" - [x-y] range in reverse order."}

In other words, \u0600 is an underscore \06ff is not a valid unicode point. — Jerry

Please put more of your code, so that at least someone can try reproducing it completely if run as is without changing anything. — Jerry

What about following code line to validate that the entire string contains only Arabic letters, whitespaces and digits using verbatim-string-literal?

Regex regex = new Regex(@"^[\u0600-\u06ff\s\d]+$");

Or with regluar string literal:

Regex regex = new Regex("^[\\u0600-\\u06ff\\s\\d]+$");

By removing ^ (begin of string) and $ (end of string) the expression would search for 1 or more strings consisting only of arabic letters, whitespaces and digits instead of validating if the entire string consists of only arabic letters, whitespaces and digits (and is not empty).
