Asp.net MVC中的重載索引操作

Question

我正在使用多語言網站，我需要先設置語言，然後使用資源文件以該語言顯示頁面。

我用了兩個索引操作是這樣的：

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Threading; 
using System.Web; 
using System.Web.Mvc; 
using System.Globalization; 
using global_vrf.GeoIpService; 

namespace global_vrf.Controllers 
    { 
    public class HomeController : Controller 
    { 
     public ActionResult Index(string language) 
    { 


     Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(language); 
     Thread.CurrentThread.CurrentUICulture = new CultureInfo(language); 

     return View(); 
    } 

    public ActionResult Index() 
    { 
     string language="en-us"; 

     return View(language); 


    } 


    } 
} 

但是當我運行的頁面，我有這樣的錯誤：

The current request for action 'Index' on controller type 'HomeController' is ambiguous between the following action methods: System.Web.Mvc.ActionResult Index(System.String) on type global_vrf.Controllers.HomeController System.Web.Mvc.ActionResult Index() on type global_vrf.Controllers.HomeController

Answer 1

只是做了一個方法：

namespace global_vrf.Controllers 
{ 
    public class HomeController : Controller 
    { 
     public ActionResult Index(string language) 
     { 
      if(String.IsNullOrWhiteSpace(language)) 
      { 
      string language="en-us"; 
      } 
      Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(language); 
      Thread.CurrentThread.CurrentUICulture = new CultureInfo(language); 

      return View(); 
     } 
    } 
} 

你不能使2種方法因爲string可能爲null。

Answer 2

[HttpPost] 
public ActionResult Index(string language) 
{ 
    Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(language); 
    Thread.CurrentThread.CurrentUICulture = new CultureInfo(language); 

    return View(); 
} 

[HttpGet] 
    public ActionResult Index() 
    { 
     string language="en-us"; 

     return View(language); 


    }
