Converting a list to Dictionary in VB
提问by Medalla
I have a list of strings. I want to create a Dictionary of string, string, with "Id" as the key for each entry and the contents of the list as the value.
我有一个字符串列表。我想创建一个字符串字典，字符串，以“Id”作为每个条目的键，以列表的内容作为值。
i.e.
IE
myList= { "string1", "string2", ...etc }
and therefore
因此
myDictionary = {{"Id1", "string1"}, {"Id2", "string2"}, ...etc}
I have been trying to create a dictionary using the List.ToDictionary method but to no avail
我一直在尝试使用 List.ToDictionary 方法创建字典但无济于事
List.ToDictionary(Of String, String)("Id", Function(p) p.key)
Any help is much appreciated.
任何帮助深表感谢。

Try something like this:-
尝试这样的事情：-
Dim list As List(of string)
Dim dict As IDictionary(Of String) = list.ToDictionary(Function(p) "Id", Function(p) p)

This is impossible. Every entry in the dictionary must have a unique key.
这是不可能的。字典中的每个条目都必须有一个唯一的键。
