从字典< string，dictionary< string，string>>中删除最后一个字符使用C＃ [英] Remove last character from dictionary<string, dictionary<string, string>> using C#

问题描述

我有

Hi,
I have

Dictionary<string, Dictionary<string, string>>

我的内部字典数据如下所示

My inner dictionary data is shown below

{
           "1": {
             "message-Code1": "   0",
             "msg-Number-Pos11": "0",
             "msg-Number-Pos21": "0",
             "msg-Number-Pos31": " "
           },
           "2": {
             "message-Code2": "   0",
             "msg-Number-Pos12": "0",
             "msg-Number-Pos22": "0",
             "msg-Number-Pos32": " "
           }

如何从每个键中删除最后一个字符，即第一组中的1和第二组中的2。



我尝试过：

How can I remove the last character from every key i.e 1 in the first set and 2 in the second set of result.

What I have tried:

var dicion = dictionary.Where(pair => pair.Value.Remove(pair.Value.Key.Last()));

推荐答案

你好不要从字典的键中删除一个字符。

但是您可以使用修改后的密钥创建一个新条目，并删除具有原始条目的条目。

You cannot remove a character from the key of the dictionary.
However you can create a new entry with the modified key and remove the entry having the original one.
