推荐答案

将方法设为静态。

make the method as static.

private static List<string> GetEmpNames()

当您执行Linq to Objects查询时，它将返回IEnumerable< Student>类型，您可以使用< a href =http://msdn.microsoft.com/en-us/library/bb342261.aspx> ToList（） [ ^ ]创建List< T>的方法来自IEnumerable< T>：

When you do the Linq to Objects query, it will return you the type IEnumerable<Student>, you can use the ToList()[^] method to create a List<T> from an IEnumerable<T>:

var selected = from s in studentCollection
                           select s;

List<Student> selectedCollection = selected.ToList();

这可能会有所帮助。
