定义

public:
 virtual void BeginRender();
public virtual void BeginRender ();

注解

BeginRender方法的类实现没有任何功能。 HtmlTextWriterThe HtmlTextWriter class implementation of the BeginRender method has no functionality. 您必须重写BeginRender从派生的HtmlTextWriter类中的方法,以提供您自己的呈现功能。You must override the BeginRender method in a class derived from HtmlTextWriter to provide your own rendering functionality. 例如,在可能需要<p>在控件之前立即呈现元素但在前面确定需要<p>元素的标记语言中,可以使用BeginRender重写。For example, in a markup language that might require <p> elements to be rendered immediately ahead of a control, but where the need for the <p> element is determined earlier, you could use the BeginRender override.
