MVC 中301永久重定向

public class PermanentRedirectResult : ViewResult

{

public string Url { get; set; }

public PermanentRedirectResult(string url)
{
    if (string.IsNullOrEmpty(url))
        throw new ArgumentException("url is null or empty", url);
    this.Url = url;
} 

public override void ExecuteResult(ControllerContext context)
{
  if (context == null)
    throw new ArgumentNullException("context");
  context.HttpContext.Response.StatusCode = 301;
  context.HttpContext.Response.RedirectLocation = Url;
  context.HttpContext.Response.End();
}

}

使用

public class ProductController : Controller

{

    public ActionResult JingSuan()
    {
        return new PermanentRedirectResult("/Controller/Action/参数");
    }

}
