您也可以使用FilteredTextBoxEntender来自AjaxControlToolkit.
然后设置FilteredTextBoxExtender的以下属性

You can also use the FilteredTextBoxEntender from the AjaxControlToolkit.
Then set following properties of the FilteredTextBoxExtender

FilterMode = Custom<br />
FilterType = InvalidChars<br />
InvalidChars = ''" 

(没有逗号，其他逗号也将被视为无效.)

(without commas else comma will also be considered invalid.)

以下代码可用于禁止TextBox中的和"

The following code can be used to disallow " and '' in TextBox

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server"

    ControlToValidate="TextBox1" ErrorMessage=" and ' are not permitted"

    ValidationExpression="[^"']*"></asp:RegularExpressionValidator>
