Asp.net MVC Render及Redirect的扩展

这个是Redirect的扩展

namespace System.Web.Mvc
{
using System;
/// <summary>
/// 对Controller的Redirect操作的扩展
/// blog:http://chsword.cnblogs.com/
/// </summary>
public static class RedirectExtension
{
/// <summary>
/// 重定向到上一个Action. 即 header 的 "HTTP_REFERER" (<c>Context.UrlReferrer</c>).
/// </summary>
static public void RedirectToReferrer(this Controller controller) {
controller.Response.Redirect(controller.Request.ServerVariables["HTTP_REFERER"]);
}
[Obsolete("已经过时请使用RedirectToReferrer")]
static public void RedirectToReferer(this Controller controller)
{
RedirectToReferrer(controller);
}
/// <summary>
/// Redirect 到站点根目录 (<c>Context.ApplicationPath + "/"</c>).
/// </summary>
static public void RedirectToSiteRoot(this Controller controller) {
controller.Response.Redirect(controller.Request.ApplicationPath + "/");
}

}
}

Pv3中已经有了,不过void的情况下不支持,还是有其可用性的

namespace System.Web.Mvc
{
using System;
using System.Text;
using System.Web.Script.Serialization;
using System.Runtime.Serialization.Json;
/// <summary>

{
c.HttpContext.Response.Write(str);
}

{

if (!string.IsNullOrEmpty(contenttype))
{
response.ContentType = contenttype;
}
else
{

}
if (encoding != null)
{
response.ContentEncoding = encoding;
}
if (data != null)
{
