创建具有两个以上参数的元组

Question

I want to convert 我想转换

List<Tuple<IntPtr, string, string>>

into 进入

Dictionary<IntPtr, Tuple<string,string>>

using 使用

ToDictionary

ie 即

var T = new List<Tuple<IntPtr, string, string>>();
T.ToDictionary(/*I cannot figure out the right syntax*/);

All examples I could find have just 2 arguments while I have 3. 我可以找到的所有示例只有2个参数，而我只有3个。

Answer 1

You should use Enumerable.ToDictionary overload which accepts both key and value selectors: 您应该使用Enumerable.ToDictionary重载，该重载同时接受键和值选择器：

T.ToDictionary(t => t.Item1, t => Tuple.Create(t.Item2, t.Item3))

But keep in mind, that there should not be duplicated pointers in your list. 但是请记住，列表中不应有重复的指针。
