通过字符串或字符索引数组 [英] indexing array through string or character

问题描述

大家好，

我正在生成类似文本框的控件，动态地为不同的主题添加标签，这些控件进一步取决于所选的标准，现在我必须交叉检查是否生成了这些控件，例如，如果我选择标准9，则主题的控件将是数学，科学等，如果我选择了11科学，那将是物理学，化学等.因为我采用了bool [] b数组，其中我指定b [0]用于数学，如果生成了数学文本框，则将其设置为true，否则是错误的.

现在我需要的是我可以像b ["Maths]] = true或b [" M] = true这样的数组吗?即是否可以使用字符串或字符??遍历或迭代到数组??

请让我知道是否可能...

谢谢&问候，

Hello everyone,

I am generating controls like textbox ,labels dynamically for different subjects which are further dependent on the standard selected now i have to cross check that which controls are generated like if i select standard 9 then controls of subjects would be of Maths, science etc and if i select 11th science then it would be physics , chemistry etc. for that i have taken an bool[] b array in which i specify that b[0] is for Maths and if maths textbox is generated then it is set to true else it is false.

Now what i need is can i have array like this b["Maths"]=true OR b["M"]=true?? i.e. is it possible to traverse or iterate to an array using string or character ??

Please let me know if it is possible ...

Thanks & Regards,

推荐答案

此类索引功能是通过以下通用类之一实现的:

• System.Collections.Generic.Dictionary<TKey, TValue>;
  http://msdn.microsoft.com/en-us/library/xfhwa508.aspx [ ^ ];
• System.Collections.Generic.SortedDictionary<TKey, TValue>;
  http://msdn.microsoft.com/en-us/library/f7fta44c.aspx [ ^ ];
• System.Collections.Generic.SortedList<TKey, TValue>;
  http://msdn.microsoft.com/en-us/library/ms132319.aspx [ ^ ].

Such indexing functionality is achieved through one of the following generic classes:

• System.Collections.Generic.Dictionary<TKey, TValue>;
  http://msdn.microsoft.com/en-us/library/xfhwa508.aspx[^];
• System.Collections.Generic.SortedDictionary<TKey, TValue>;
  http://msdn.microsoft.com/en-us/library/f7fta44c.aspx[^];
• System.Collections.Generic.SortedList<TKey, TValue>;
  http://msdn.microsoft.com/en-us/library/ms132319.aspx[^].
