访问像数组一样的Viewbag？ [英] Access a Viewbag like an Array?

问题描述

假设一个名为

的视图包

  ViewBag.Modes 
  

包含以下内容：

$ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $
手动
完成

如何通过索引访问视图包一个数组？

例如Simple在索引0处，它看起来像这样

  ViewBag.Modes [0] 
  

我尝试了上述方法，但它不起作用...如何复制这与viewbag或有我可以使用的解决方法？

解决方案

感谢您的帖子，但很快在写这篇文章之后，我使用模型&列表如下所示，这也可以使用viewbag而不是model完成。

 列表< string> list = new List< string>（）; 
 foreach（Models.AppModeInfo blah in Model.theAppModes）
 {
 list.Add（blah.Name）; 
} 
 
 var AppModeText =; 
 switch（item.AppModeId）
 {
案例1：
 AppModeText = list [0]; 
休息; 
案例2：
 AppModeText = list [1]; 
休息; 
案例3：
 AppModeText = list [2]; 
休息; 
案例4：
 AppModeText = list [3]; 
休息; 
案例5：
 AppModeText = list [4]; 
休息; 
} 
  

Imagine a view bag called

 ViewBag.Modes

this contains the following:

Simple
Advanced
Manual
Complete

How can I access the viewbag by index like you would in an array?

e.g Simple is at index 0 then it would look like this

ViewBag.Modes[0]

I tried the above but it doesn't work so...How can I replicate this with viewbag or is there a workaround I can use?

解决方案

Thanks for the posts but shortly after writing this I came up with this solution using a model & list as below this could also be done using viewbag instead of model.

List<string> list = new List<string>();
            foreach (Models.AppModeInfo blah in Model.theAppModes)
            {
                list.Add(blah.Name);
            }

            var AppModeText = "";
            switch (item.AppModeId)
            {
                case 1:
                    AppModeText = list[0];
                    break;
                case 2:
                    AppModeText = list[1];
                    break;
                case 3:
                    AppModeText = list[2];
                    break;
                case 4:
                    AppModeText = list[3];
                    break;
                case 5:
                    AppModeText = list[4];
                    break;
            }
