本文介绍如何利用ResponseHelper类实现页面跳转，包括基本用法和不同场景下的应用，详细解释了如何通过Redirect方法调整目标窗口和窗口特征。

//新窗口类
public static class ResponseHelper
{
    public static void Redirect(string url, string target, string windowFeatures)
    {
        HttpContext context = HttpContext.Current;
        if ((String.IsNullOrEmpty(target) || target.Equals("_self", StringComparison.OrdinalIgnoreCase)) && String.IsNullOrEmpty(windowFeatures))
        {
            context.Response.Redirect(url);
        }
        else
        {
            Page page = (Page)context.Handler;
            if (page == null)
            {
                throw new InvalidOperationException("Cannot redirect to new window outside Page context.");
            } url = page.ResolveClientUrl(url);
            string script;
            if (!String.IsNullOrEmpty(windowFeatures))
            {
                script = @"window.open(""{0}"", ""{1}"", ""{2}"");";
            } else
            {
                script = @"window.open(""{0}"", ""{1}"");";
            }
            script = String.Format(script, url, target, windowFeatures);
            ScriptManager.RegisterStartupScript(page, typeof(Page), "Redirect", script, true);
        }
    }
}
