            else
            {

            }
            script = String.Format(script, url, target, windowFeatures);

用的时候直接调用就可以了

调用方法
windowFeatures是设置窗体，可以为空
Redirect("http://www.baidu.com/", "_blank","");
Redirect("http://www.baidu.com/", "_blank", "'height=100, width=400, top=0, left=0, toolbar=no, menubar=no, scrollbars=no, resizable=no,location=no, status=no'");
其实也是利用了window.open() , 换而言之，也可以用
Response.Writer("<script language=javascript>window.open('test.html','newwindow','');</script>");
