如何将两个列表组合到List <KeyValuePair <>>？

Question

有两个列表:

List<string> files;
List<Filter> filters;

我希望结果如下:

List<KeyValuePair<string, Filter>> fileFilterMap;

我尝试了几个东西(lambda表达式,linq)但失败了.我真的不想要

for(int i = 0; i< files.count; i++)

方法.

Answer 1

您可以使用:

List<KeyValuePair<string, Filter>> fileFilterMap =
  Enumerable.Range(0, files.Count)
  .Select(i => new KeyValuePair<string, Filter>(files[i], filters[i]))
  .ToList();

要么:

List<KeyValuePair<string, Filter>> fileFilterMap =
  Enumerable.Zip(
    files,
    filters,
    (file, filter) => new KeyValuePair<string, Filter>(file, filter)
  )
  .ToList();

Answer 2

看看Enumerable.Zip。

var fileFilterMap = Enumerable.Zip(files, filters, (file, filter) => new KeyValuePair(file, filter));
