从 MVC 控制器中的多个操作运行单个方法

Question

我的控制器中的多个操作方法具有相同的以下代码。是否可以将其简化为单个方法并将多个操作路由到它？

[HttpGet]
public ActionResult Tool2(Guid? id)
{
    var model = _viewModelFactory.CreateViewModel<Guid?, ToolsViewModel>(id);

    return model.ReferenceFound ? View(model) : View("~/Views/Tools/InvalidReference.cshtml", model);
}

[HttpGet]
public ActionResult Tool1(Guid? id)
{
    var model = _viewModelFactory.CreateViewModel<Guid?, ToolsViewModel>(id);

    return model.ReferenceFound ? View(model) : View("~/Views/Tools/InvalidReference.cshtml", model);
}

每个动作都有一个独特的视图，这需要保留。

创建一个两个动作都会调用的通用方法。将这两个操作分开，因为它比编写（和阅读！）自定义路由更容易理解。

public ActionResult Tool1(Guid? guid)
{
    return CommonAction(guid, "Tool1");
}

public ActionResult Tool2(Guid? guid)
{
    return CommonAction(guid, "Tool2");
}

private ActionResult CommonAction(Guid? guid, string viewName)
{
    var model = _viewModelFactory.CreateViewModel<Guid?, ToolsViewModel>(id);
    return model.ReferenceFound ?
        View(model) : View("~/Views/Tools/InvalidReference.cshtml", model);
}
