使用OrderBy对List<Person>集合排序
string sortOrder = Request.QueryString["sortOrder"];
string sortField = Request.QueryString["sortField"];
List<Person> lstPer = new List<Person>();
List<Person> lstPerDesc = new List<Person>();//降序排序结果
List<Person> lstPerAsc = new List<Person>();//升序排序结果
for (int j = 0; j < 10; j++)
{
lstPer.Add(new Person() { ID = j, UserName = Guid.NewGuid().ToString() });
}
if (!string.IsNullOrEmpty(sortField) && !string.IsNullOrEmpty(sortOrder))
{
if (sortOrder.ToUpper() == "DESC")
{
lstPerDesc = lstPer.OrderByDescending(o => o.GetType().GetProperty("ID").GetValue(o, null)).ToList();
}
else
{
lstPerAsc = lstPer.OrderBy(o => o.GetType().GetProperty("ID").GetValue(o, null)).ToList();
}
}
public class Person
