.Net正则表达式ValidationExpression ASCII [英] .Net Regex ValidationExpression ASCII

问题描述

任何人都知道一个很好的Regex表达式可以放入ValidationExpression中，以确保我的用户仅输入ASCII字符吗?

Anyone know a good Regex expression to drop in the ValidationExpression to be sure that my users are only entering ASCII characters?

<asp:RegularExpressionValidator id="myRegex" runat="server" ControlToValidate="txtName" ValidationExpression="???" ErrorMessage="Non-ASCII Characters" Display="Dynamic" />

推荐答案

您可能要注意的一件事是ASCII表的下部有很多控制字符，这些字符可能导致时髦的结果.这是我仅允许使用非时髦"字符的表达式:

One thing you may want to watch out for is the lower part of the ASCII table has a lot of control characters which can cause funky results. Here's the expression I use to only allow "non-funky" characters:

^([^\x0d\x0a\x20-\x7e\t]*)$
