HtmlTextWriterTag 列舉值,否則,如果 tagName 未與特定的 HtmlTextWriterTag 值有關聯,則為 UnknownThe HtmlTextWriterTag enumeration value; otherwise, if tagName is not associated with a specific HtmlTextWriterTag value, Unknown.

範例

下列程式碼範例示範如何覆寫RenderBeginTag接受字串做為其參數之方法的多載。The following code example shows how to override the overload of the RenderBeginTag method that takes a string as its parameter. 字串GetTagKey會傳遞至方法,以將它轉換為對應HtmlTextWriterTag的列舉成員, RenderBeginTag然後將該字串傳遞至使用HtmlTextWriterTag列舉值做為參數的多載。The string is passed to the GetTagKey method, which converts it to the corresponding HtmlTextWriterTag enumeration member, and then passes that to the RenderBeginTag overload that takes a HtmlTextWriterTag enumeration value as a parameter.

virtual void RenderBeginTag( String^ tagName ) override
{
   
   // Call the overloaded RenderBeginTag(HtmlTextWriterTag) method.
   RenderBeginTag( GetTagKey( tagName ) );
}
public override void RenderBeginTag(string tagName)
{
    // Call the overloaded RenderBeginTag(HtmlTextWriterTag)
    // method.
    RenderBeginTag(GetTagKey(tagName));
}
Public Overloads Overrides Sub RenderBeginTag(ByVal tagName As String)
    ' Call the overloaded RenderBeginTag(HtmlTextWriterTag) method.
    RenderBeginTag(GetTagKey(tagName))
End Sub

備註

如果tagName GetTagKey Unknownnull、空字串(""),或在標記標記名稱的資料表中找不到,則方法會傳回欄位。If tagName is null, an empty string (""), or cannot be found in the table of markup tag names, the GetTagKey method returns the Unknown field.
