如何在C＃.net中分配值时分配数组的键


How can i assign a key of a array on the time of assigning a value in C#.net

我是ASP.NET的新手，我想在数据库中插入动态表单中的数据。为了标识字段，我还保存了数据库中字段的标签。

为此，我想使用多维数组。问题是，我想在分配值时声明数组的键，就像下面在PHP中所做的那样：

1
myarray['key_label'] = 'key_value';

我不知道如何在C.NET中实现这一点。为此，我搜索并找到了字典，所以我使用了以下代码，但在这种情况下，我可以一次查看任何键或值：

1
2
3
4
 var dictionary = new Dictionary<string, object>();
 dictionary.Add("username", rpu);
 dictionary.Add("sec_username", rcu);
 dictionary.Add("co_type", ct);

请引导我到下面

  • 如何分配上面提到的数组的值？

  • 我找到了一种同时显示键和值的方法，如下所述，但是我是否可以像处理数组那样使字典具有多维性？

    Dictionary<int, string> plants = new Dictionary<int, string>() {    
    {1,"Speckled Alder"},    
    {2,"Apple of Sodom"},    
    {3,"Hairy Bittercress"},    
    {4,"Pennsylvania Blackberry"},    
    {5,"Apple of Sodom"},    
    {6,"Water Birch"},    
    {7,"Meadow Cabbage"},    
    {8,"Water Birch"}    
    };

    Response.Write("dictionary elements........<br />");

    //loop dictionary all elements  
    foreach (KeyValuePair<int, string> pair in plants)
    {
        Response.Write(pair.Key +"....." + pair.Value +"<br />");
    }

    //find dictionary duplicate values.  
    var duplicateValues = plants.GroupBy(x => x.Value).Where(x => x.Count() > 1);

    Response.Write("<br />dictionary duplicate values..........<br />");

    //loop dictionary duplicate values only            
    foreach (var item in duplicateValues)
    {
        Response.Write(item.Key +"<br />");
    }

    }

how can I assign the value of an array like I mentioned above?
</p>
</blockquote>

<p>
Yes, you can access a dictionary entry in C# like you would an array in PHP. Something like <wyn>myDictionary["keyOne"] = varOne;</wyn>
</p>

<blockquote>

I found a way to display both key and values together, mentioned below
  but is it possible that i can make dictionary multi dimensional like
  we do for arrays?
</p>
</blockquote>

<p>
Yes, like in PHP where you make an array of arrays, you would in C# create a dictionary of dictionaries:
</p>

[cc lang="csharp"]Dictionary<string,Dictionary<string,object>> multiDict = new Dictionary<string,Dictionary<string,object>>();
multiDict["dictionary1"]["keyOne"] = varOne;
