正确例子：调用方法

 
        DllInfoItem info = null;

        string preUrl = "../ViewTable/default.aspx?dll=";
        string url = null;
        string cssClass = "DefaultHref";
        string aHref = null;

        for (int i = 0; i < iCount; ++i)
        {
            rpItem = rp_List.Items[i];

            info = theList[i];

            url = preUrl + HttpUtility.UrlEncode(info.TheName);
            aHref = ch.AHrefGet(url, info.TheName, info.TitleGet(), cssClass, true);

            itxt = rpItem.FindControl(ci.lt_TheName) as ITextControl;
            itxt.Text = aHref;

        }

                string cssClass,

            )
        {
            StringBuilder theResult = new StringBuilder();

            theResult.Append("<a ");

            if (url != null && url.Length > 0)
            {
                theResult.Append(" href=\"" + url.Replace("\"", "&quot;") + "\"");
            }

            if (theTitle != null && theTitle.Length > 0)
            {
                theResult.Append(" title=\"" + theTitle.Replace("\"", "&quot;") + "\"");
            }

            if (cssClass != null && cssClass.Length > 0)
            {
                theResult.Append(" class=\"" + cssClass.Replace("\"", "&quot;") + "\"");
            }

            if (isTargetBlank)
            {
                theResult.Append(" target=\"_blank\"");
            }

            theResult.Append(">" + theName + "</a>");

            return theResult.ToString();
        }

（下面是错误的例子：把class的属性固定成class="DefaultHref"写到原子方法里面了，失去了扩展能力）
