BoundField.HtmlEncode 属性

定义

获取或设置一个值,该值指示在 BoundField 对象中显示字段值之前,是否对这些字段值进行 HTML 编码。

public:
 virtual property bool HtmlEncode { bool get(); void set(bool value); };
public virtual bool HtmlEncode { get; set; }
member this.HtmlEncode : bool with get, set
Public Overridable Property HtmlEncode As Boolean

属性值

如果在 BoundField 对象中显示字段值之前,对这些字段值进行 HTML 编码,则为 true;否则为 false。 默认值为 true

示例

下面的代码示例演示如何使用 HtmlEncode 属性来防止字段值在对象中 BoundField 显示之前进行 HTML 编码。

注解

HtmlEncode使用 属性指定在对象中BoundField显示字段值之前,是否将其 HTML 编码为各自的字符串表示形式。 例如,如果此属性为 true,则“script>”<的字符串值将呈现为“<script>”。 如果此属性为 false,则字符串将保持不变。

注意

HTML 编码字段值有助于防止显示跨站点脚本攻击和恶意内容。 应尽可能启用此属性。
