如何将项添加到Dictionary <string,Dictionary <string,object >>？

Question

我希望我的LayoutManager类的用户能够写这个:

LayoutManager layoutManager = new LayoutManager();
layoutManager.AddMainContentView("customers", "intro", 
    new View { Title = "Customers Intro", Content = "This is customers intro." });

但是我需要在下面的AddMainContentView()中的字典中填写这个字典的语法是什么？

public class LayoutManager
{
    private Dictionary<string, Dictionary<string, object>> _mainContentViews = new Dictionary<string, Dictionary<string, object>>();
    public Dictionary<string, Dictionary<string, object>> MainContentViews
    {
        get { return _mainContentViews; }
        set { _mainContentViews = value; }
    }

    public void AddMainContentView(string moduleKey, string viewKey, object view)
    {
        //_mainContentViews.Add(moduleKey, new Dictionary<string, object>(viewKey, view));
        //_mainContentViews.Add(moduleKey, viewKey, view);
        _mainContentViews.Add(moduleKey, ???);
    }

    ...
}

Answer 1

public void AddMainContentView(string moduleKey, string viewKey, object view)
{
    Dictionary<string, object> viewDict = null;
    if (!MainContentViews.TryGetValue(moduleKey, out viewDict)) {
        viewDict = new Dictionary<string, object>();
        MainContentViews.Add(moduleKey, viewDict);
    }
    if (viewDict.ContainsKey(viewKey)) {
        viewDict[viewKey] = view;
    } else {
        viewDict.Add(viewKey, view);
    }
}
