備註

使用 Underline 屬性,即可指定或判斷字型是否在文字底下包含一行。Use the Underline property to specify or determine whether the font contains a line under the text.

這個屬性的值會儲存在 view 狀態中。The value of this property is stored in view state.

注意

LinkButton HyperLink HtmlAnchor 由設定控制項的和屬性,會影響、和控制項所產生 StrikeoutOverline 連結的字型底線行為 FontInfoThe font underline behavior for links generated by the LinkButton, HyperLink, and HtmlAnchor controls is affected by setting the Strikeout and the Overline properties of the FontInfo for the control. 如果 Strikeout Overline 設定或屬性,不論其值為何,您都必須明確地設定此 Underline 屬性(如果您想要將連結加上底線)。If the Strikeout or the Overline properties are set, regardless of their value, you must set the Underline property explicitly if you want the link to be underlined.
