C#字典组成

Question

假设我有一份A的仲裁清单

class A
{
string K {get;set;}
string V {get;set;}
}

...
List<A> theList = ...

有没有一种简单的方法从列表中组成字典？(如下所示)

Dictionary<string, string> dict = magic(x => x.K, x => x.V, theList)

我不想写下面的代码:

var d = new Dictionary<string, string>
foreach(var blah in theList)
    d[blah.K] = blah.V

Answer 1

就是这样:Enumerable.ToDictionary.

你这样使用它:

Dictionary<string, string> dict = theList.ToDictionary(e => e.K, e => e.V);
