通过

HttpCapabilitiesBase.RequiresOutputOptimization 属性

  • 参考

定义

命名空间:
System.Web.Configuration
程序集:
System.Web.dll

获取一个值，该值指示浏览器是否要求页中包含一个经过大小优化的标记语言标记的窗体。

public:
 virtual property bool RequiresOutputOptimization { bool get(); };
public virtual bool RequiresOutputOptimization { get; }
member this.RequiresOutputOptimization : bool
Public Overridable ReadOnly Property RequiresOutputOptimization As Boolean

属性值

Boolean

如果浏览器要求页中包含一个经过大小优化的标记语言标记的窗体，则为 true；否则为 false。 默认值为 false。

示例

下面的代码示例演示如何确定浏览器是否需要页面包含大小优化形式的标记语言标记。

<%@ page language="C#"%>

    }

    void CheckBrowserCaps()
    {
        String labelText = "";
        System.Web.HttpBrowserCapabilities myBrowserCaps = Request.Browser;
        if (((System.Web.Configuration.HttpCapabilitiesBase)myBrowserCaps).RequiresOutputOptimization)
        {
            labelText = "Browser requires pages to contain a size-optimized form of markup language tags.";
        }
        else
        {
            labelText = "Browser does not require pages to contain a size-optimized form of markup language tags.";
        }

        Label1.Text = labelText;
    }
</script>

    Function CheckBrowserCaps()

        Dim labelText As String = ""
        Dim myBrowserCaps As System.Web.HttpBrowserCapabilities = Request.Browser
        If (CType(myBrowserCaps, System.Web.Configuration.HttpCapabilitiesBase)).RequiresOutputOptimization Then
            labelText = "Browser requires pages to contain a size-optimized form of markup language tags."
        Else
            labelText = "Browser does not require pages to contain a size-optimized form of markup language tags."
        End If

        Label1.Text = labelText

    End Function 'CheckBrowserCaps
</script>

    <title>Browser Capabilities Sample</title>
</head>
<body>
    <form runat="server" id="form1">
        <div>
            Browser Capabilities:
            <p/><asp:Label ID="Label1" Runat="server" />
        </div>
    </form>
</body>
</html>

注解

如果 true为 ，则服务器控制适配器将生成最小输出，以减小生成的页面的大小。

注意

属性 RequiresOutputOptimization 返回 true i 模式兼容的浏览器。
