用ASP.NET刷新页面的几种有效方法

第一：(需替换<>) 
<script><!-- 
var limit="3:00" 
if ( document.images ) 
{ 
    var parselimit=limit.split( ":" )parselimit=parselimit[0]*60+parselimit[1]*1 
} 
function beginrefresh( ) 
{ 
    if ( !document.images )returnif ( parselimit==1 )window.location.reload( )else 
    { 
        parselimit-=1curmin=Math.floor( parselimit/60 )cursec=parselimit% 60if ( curmin!=0 )curtime=curmin+"分"+cursec+"秒后重刷本页！"elsecurtime=cursec+ "秒后重刷本页！"window.status=curtimesetTimeout( "beginrefresh( )",1000 ) 
    } 
} 
window. style="Z-INDEX: 102; LEFT: 408px; POSITION: absolute; TOP: 232px" s_positioning="text2D"><P><FONT size="3">自动刷新页面</FONT></P> 
</DIV>
第二： 
<meta http-equiv="refresh" content="300;url=target.html">
第三： 
private void Button2_Click( object sender, System.EventArgs e )   
{ 
    Response.Write( " 
    <script language=javascript>window.location.href=document.URL; 
    </script>" ); 
} 
第四： 
private void Button3_Click( object sender, System.EventArgs e )   
{ 
    Response.AddHeader( "Refresh","0" ); 
} 
第五： 
private void Button6_Click( object sender, System.EventArgs e )   
{ 
    //好像有些不对？ 
    //Response.Write("<script language=javascript>window.location.reload( );</script>" ); 
} 
第六： 
private void Button1_Click( object sender, System.EventArgs e )   
{ 
    Response.Redirect( Request.Url.ToString( ) ); 
}
