LINQ to SQL和有序结果的总计

使用闭包和匿名方法：

List<Item> myList = FetchDataFromDatabase();decimal currentTotal = 0;var query = myList    .OrderBy(i => i.Date)    .Select(i =>      {       currentTotal += i.Amount;       return new { Date = i.Date, Amount = i.Amount, RunningTotal = currentTotal        };     });foreach (var item in query){    //do with item}
