## ASP.NET MVC 中如何获取控制器的名称

+ 视图中
```csharp
string controller =ViewContext.RouteData.Route.GetRouteData(this.Context).Values["controller"].ToString();
string controller = ViewContext.RouteData.Values["controller"].ToString();
```

+ 控制器的action中
```csharp
string controller = RouteData.Route.GetRouteData(this.HttpContext).Values["controller"].ToString();
string controller = RouteData.Values["controller"].ToString();
```

+ 过滤器中
```csharp
/// <summary>
/// 过滤器中
/// </summary>
/// <param name="filterContext"></param>
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
   base.OnActionExecuting(filterContext);
　 string controller = filterContext.RouteData.Values["controller"].ToString(); 
   controller = controller + "Controller";
}
```

+ 公共方法中
```csharp
/// <summary>
/// 获取当前页面的Controller全名称
/// </summary>
/// <returns></returns>
public string GetCurrentController(){
      string controller = HttpContext.Current.Request.RequestContext.RouteData.Values["controller"].ToString();
      if (!string.IsNullOrWhiteSpace(controller)){
                controller = controller + "Controller";}
      else{ controller = "";}
      return controller;
}
```
