ASP.NET显示提示窗口、打开页面

Response.Write("<script language=javascript>alert('"+"test" +"');</script>") ;//显示提示框
Response.Write("<script language='javascript'>window.open(test.aspx');</script>"); //打开新的网页
Response.Write("<script language='javascript'>window.location='test.aspx'</script>"); //在原有页面上跳转
ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "js", "alert('密码错误！');", true);//隐式刷新

PS：注意中英文符号
