Refer这并学习如何编写正则表达式：

这里有些人创建了正则表达式

请参考这个类似的主题好吧

尝试使用以下表达式的正则表达式验证器
Try a Regular expression validator with the below expression
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" ControlToValidate="TextBox1"
ValidationExpression="^\d+(\.\d{1,1})?
runat = server ErrorMessage = RegularExpressionValidator > < / asp：RegularExpressionValidator >
" runat="server" ErrorMessage="RegularExpressionValidator"></asp:RegularExpressionValidator>
