Question

如何将list作为linq的数据源进行排序

ExtAspNet.GridColumn column = Grid.Columns[Grid.SortColumnIndex];
list = Maintain.LinqSort.OrderBy(list, column.SortField + " " + column.Grid.SortDirection).ToList();
Grid.DataSource = list;

这样写报错，请问应该怎么做

Answer 1

List<int> lst = new List<int>() {3,4,2,1 };
lst = lst.OrderBy(item => item).ToList();
foreach (int i in lst)
{
MessageBox.Show(i.ToString());
}
输出的字符是按升序排列的，如果降序使用OrderByDescending
多个条件排序后面的写ThenBy或ThenByDescending
