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 = < span class =code-keyword> RegularExpressionValidator > < / asp：RegularExpressionValidator >

" runat="server" ErrorMessage="RegularExpressionValidator"></asp:RegularExpressionValidator>
