假设我有一个词典＆LT;字符串，元组LT; T1，T2＆GT;＆GT; ，我想，以确定是否任何字典值有V1其T1。我将如何做到这一点最优雅？

Suppose I have a Dictionary<String, Tuple<T1,T2>> and I want to determine if the any of the dictionary values has V1 for its T1. How would I do this most elegantly?

LINQ的？

那么，这想到的：

var exists = dict.Values.Any(t => t.Item1 == v1);
