Question

我想对下面的'周'进行排序。 'InvalidCast Exception'告诉我，我甚至不接近（无论我抛出什么）。

sortedWeeks在调试器中看起来不错......

如何让它回到课堂上？

我实际上并不需要原来的Weeks类，因为它将通过JavaScriptSerializer运行......虽然我想知道如何对这个类进行排序......

Weeks theData = new Weeks();
// pretend its now full of data and I need the weeks sorted on number
var sortedWeeks = theData.weeks.OrderBy(x => x.number);

theData.weeks = sortedWeeks;  // <--- How do I cast this??

public class Weeks
{
     private List<Week> _weeks = new List<Week>();
     public List<Week> weeks
     {
         get { return _weeks; }
         set { _weeks = value; }
      }
}
public class Week
{
     public string week { get; set; }
     public string file { get; set; }
     public int number { get; set; }
 }

Answer 1

theData.weeks = sortedWeeks.ToList();

Answer 2

theData.weeks.OrderBy（x =＆gt; x.number）;将返回IEnumerable<Week>或IQueryable<Week>您需要ToList（）来关闭查询并为您提供一个列表。另一种方法是将Weeks属性设为IEnumerable<Week>
