C# 服务器标记的格式不正确-RegularExpressionValidator

我正在尝试编写一个RegularExpressionValidator，它检查文本框中的条目是否为整数（不包含“.”或“，”，只包含像“500”这样的整数值）

但我遇到过这样的情况：

Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.

Parser Error Message: The server tag is not well formed.

代码如下：

<asp:TextBox ID="Paymenttb" runat="server"></asp:TextBox>
<asp:RegularExpressionValidator ID ="PaymentValidator" runat="server" ControlToValidate="Paymenttb" 
ErrorMessage="Payment must be of type Int (No "." or "," for example)." ValidationExpression="^\d+$">*</asp:RegularExpressionValidator>

*

这有什么问题？

我已经四处搜索，找不到任何原因来解释为什么格式不正确。

您的

ErrorMessage

属性格式不正确：

ErrorMessage="Payment must be of type Int (No "." or "," for example)."

您需要对属性值中的

“

进行转义-将它们加倍：

ErrorMessage="Payment must be of type Int (No ""."" or "","" for example)."

或者，使用单引号分隔属性值：

ErrorMessage='Payment must be of type Int (No "." or "," for example).'

这部分。在引用的参数中有引号

您可以通过将外部引号设置为单引号来解决此问题：

ErrorMessage='Payment must be of type Int (No "." or "," for example).'

另一种解决方案：转义引号html样式：

ErrorMessage="Payment must be of type Int (No "." or "," for example)."

试试这个

<asp:TextBox ID="Paymenttb" runat="server"></asp:TextBox>


<asp:RegularExpressionValidator ID ="RegularExpressionValidator1" runat="server" ControlToValidate="Paymenttb"  ToolTip="Payment must be of type Int (No '.' or ',' for example)." ValidationExpression="^\d+$">*</asp:RegularExpressionValidator>

试试这个

<asp:TextBox ID="Paymenttb" runat="server"></asp:TextBox>


<asp:RegularExpressionValidator ID ="RegularExpressionValidator1" runat="server" ControlToValidate="Paymenttb"  ToolTip="Payment must be of type Int (No '.' or ',' for example)." ValidationExpression="^\d+$">*</asp:RegularExpressionValidator>
