BoundField.HtmlEncode 属性

  • 参考

定义

命名空间:
System.Web.UI.WebControls
程序集:
System.Web.dll

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

Boolean

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。
