重要

此示例具有一个接受用户输入的文本框,这是一个潜在的安全威胁。This example has a text box that accepts user input, which is a potential security threat. 默认情况下,ASP.NET 网页验证用户输入是否不包含脚本或 HTML 元素。By default, ASP.NET Web pages validate that user input does not include script or HTML elements. 有关详细信息,请参阅脚本侵入概述For more information, see Script Exploits Overview.

注解

除了属性外,还可以使用此属性 ShowMessageBox 来控制验证摘要的显示位置。This property can be used in addition to the ShowMessageBox property to control where the validation summary is displayed. 如果将此属性设置为 true ,则验证摘要将显示在网页上。If this property is set to true, the validation summary is displayed on the Web page.

备注

如果 ShowMessageBoxShowSummary 属性都设置为 true ,则验证摘要将显示在消息框和网页上。If both the ShowMessageBox and ShowSummary properties are set to true, the validation summary is displayed in both a message box and on the Web page.
