Gets or sets a scheme attribute used to interpret the metadata property value defined by the HtmlMeta control.

Namespace:   System.Web.UI.HtmlControls
Assembly:  System.Web (in System.Web.dll)

public virtual string Scheme { get; set; }

Property Value

Type: System.String

The scheme attribute.

The Scheme property allows you to specify a scheme attribute of the rendered HTML <meta> element. The scheme attribute can be used to provide user agents, such as client browsers or search engines, additional context for interpreting the metadata property.

The Scheme property is rendered to the scheme attribute of the resulting HTML <meta> element.

The following code example demonstrates how to use the HtmlMeta control to define HTML <meta> elements for a Web page. Two <meta> tags are defined, one listing keywords describing the page and one listing the date the page was created. The Scheme property is used for the date-related <meta> tag to aid user agents reading the date value.
