RegularExpressionValidator和Regex结果不同[已解决]

问题描述

通过RegularExpressionValidator控件进行测试:

Testing Through RegularExpressionValidator control:

<asp:TextBox ID="TextBox1" runat="server"

    ValidationGroup="Regex"></asp:TextBox>
&nbsp;
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server"

    ControlToValidate="TextBox1" ErrorMessage="Invalid"

    ValidationExpression="[0-9]{0,5}" ValidationGroup="Regex"></asp:RegularExpressionValidator>
 <asp:Button ID="btnTestRegex" runat="server" Text="Valid Or Not?"

    ValidationGroup="Regex" />

输入:
TextBox1.Text ="1a";
输出:
无效.
------------------------------- ****** ------------- --------------------
通过编码:

Input:
TextBox1.Text = "1a";
Output:
Invalid.
-------------------------------******---------------------------------
Through Coding :

<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
                            &nbsp;&nbsp;
                            <asp:Label ID="lblValid" runat="server" Text="Valid" Visible="false"></asp:Label>
                            &nbsp;&nbsp;
                            <asp:Label ID="lblInvalid" runat="server" Text="Invalid" Visible="false"></asp:Label>
                            &nbsp;&nbsp;
                            <asp:Button ID="Button3" runat="server" onclick="Button2_Click" Text="Button" />

输入:
TextBox1.Text ="1a";
输出:
有效.

Input:
TextBox1.Text = "1a";
Output:
Valid.
