c# - 请求一个 linq 来操作数组的数组

Question

我有一个包含以下元素的数组

{Mark=90, Students={"Tom","Marry","Jack"}},
{Mark=50, Students={"Niko","Gary","David"}},
{Mark=70, Students={"John","Andy","Amy"}}

我想要一个 Linq 语句将它们转换成

{Mark=90, name="Tom"},
{Mark=90, name="Marry"},
{Mark=90, name="Jack"},
{Mark=50, name="Niko"},
{Mark=50, name="Gary"},
{Mark=50, name="David"},
{Mark=70, name="John"},
{Mark=70, name="Andy"},
{Mark=70, name="Amy"}

我该怎么办？

您可以转换到匿名类(如果您需要当前方法之外的序列，则可以转换到真实类):

var results = from x in myArray
              from s in x.Students
              select new { x.Mark, name = s };
