Minimum 6 characters regex expression

Question

Minumum 6 letter checks textbox in asp.net.

I m looking for all letters and numbers, but I need it for all characters.

Answer 1

If I understand correctly, you need a regex statement that checks for at least 6 characters (letters & numbers)?

/[0-9a-zA-Z]{6,}/

Answer 2

Something along the lines of this?

<asp:TextBox id="txtUsername" runat="server" />

<asp:RegularExpressionValidator
id="RegularExpressionValidator1"
runat="server"
ErrorMessage="Field not valid!"
ControlToValidate="txtUsername"
ValidationExpression="[0-9a-zA-Z]{6,}" />

Answer 3

This match 6 or more any chars but newline :

/^.{6,}$/
