在PageLoad中调用下面的方法Position，注意StringBuilder属于System.Text命名空间

private void Position(){              RegisterHiddenField("ScrollPostion", "0");       StringBuilder getPosition = new StringBuilder();       getPosition.Append("<script language=javascript>");              getPosition.Append("function get(){");              getPosition.Append("document.forms[0].__SCROLLPOS.value = thebody.scrollTop;");       getPosition.Append("}");              getPosition.Append("thebody.onscroll=saveScrollPosition;");             getPosition.Append("</script>");       ClientScript.RegisterStartupScript(typeof(Page),"savePosition",getPosition.ToString());       if (IsPostBack)       {                StringBuilder setPosition = new StringBuilder();                setPosition.Append("＜script language='javascript'＞");                setPosition.Append("function setScrollPosition() {");                setPosition.Append(" thebody.scrollTop = " + Request["ScrollPostion"] + ";");                setPosition.Append("}");                setPosition.Append("thebody.onload=setScrollPosition;");                setPosition.Append("＜/script＞");                RegisterStartupScript("setScroll", setPosition.ToString());        }}
