Linq Zip麻烦

Question

var zip = testNames.Zip(testNumbers, (code, state) => code + ": " + state); 

给了我一个IEnumberable字符串，我怎样才能获得IEnumberable字符串字符串？

Answer 1

根据你在问题中给我们的内容，你有两个选择：

var testNames = new [] { "A", "B" };
var testNumbers = new [] { 1, 2 };

var zip1 = testNames.Zip(testNumbers, (code, state) => new { code, state });

var zip2 = testNames.Zip(testNumbers, (code, state) => (code, state));

两者都是有效的C＃。

根据您之前的question阅读情况，您需要了解此.Zip方案。您应该能够在单个查询中读取原始数据。我的answer向您展示了如何。
