C# Linq中行到列的动态转换

我想将行转换为列，实际上我可以实现静态的行到列，如下所示，但它只有在我事先知道行的位置时才起作用，所以有人知道如何在Linq中动态地将行转换为列吗

这是

这是静态代码：

var table=(from x in Mst_LocationItems

group x by x.ItemCode into gr
select new
       {
          ItemCode=gr.Key,
          LOC001 = gr.Where(x=>x.LocationID == "LOC001").Sum(x=>x.Reorder),
          LOC002 = gr.Where(x=>x.LocationID == "LOC002").Sum(x=>x.Reorder),
          LOC003 = gr.Where(x=>x.LocationID == "LOC003").Sum(x=>x.Reorder)
       }).ToList();

           table.Dump();

你能给我更多关于我的编码的细节吗？你能提供更多关于“动态”对你意味着什么的细节吗？

var table=(from x in Mst_LocationItems

group x by x.ItemCode into gr
select new
       {
          ItemCode=gr.Key,
          LOC001 = gr.Where(x=>x.LocationID == "LOC001").Sum(x=>x.Reorder),
          LOC002 = gr.Where(x=>x.LocationID == "LOC002").Sum(x=>x.Reorder),
          LOC003 = gr.Where(x=>x.LocationID == "LOC003").Sum(x=>x.Reorder)
       }).ToList();

           table.Dump();
