示例代码:

//1.IEnumerable数据转为DataTable
List<UserInfo> users = new List<UserInfo>();
users.Add(new UserInfo() { Id = 1, Name = "Newcats" });
users.Add(new UserInfo() { Id = 2, Name = "Huang" });
DataTable r1 = users.ToDataTable();

//2.DataTable数据转为List
List<UserInfo> r2 = r1.ToList<UserInfo>();

//3.根据condition条件,判断是否加入当前list集合
users.AddIf(new UserInfo() { Id = 3, Name = "NewcatsHuang" }, "newcats".Length == 0);

//4.元素不为null,则加入当前list集合
UserInfo u1 = null;
users.AddIfNotNull(u1);

//5.若集合为空,则抛异常
users.ThrowIfEmpty();

//6.若集合为null或者空,则抛异常
users.ThrowIfNullOrEmpty();

//7.判断集合是否为null或者空
bool r3 = users.IsNullOrEmpty();//=>false

//8.获取枚举项的Description特性描述
string r4 = Season.Spring.GetDescription();//=>春季

//9.获取枚举项的枚举描述类

//19.转换对象为json字符串(使用System.Text.Json)
string r14 = users[0].ToJson();//=>{"Id":1,"Name":"Newcats","UserId":null,"JoinTime":"0001-01-01 00:00:00.000"}

//20.把json字符串反序列化为对象(使用System.Text.Json)
UserInfo r15 = r14.Deserialize<UserInfo>();//=>r15.Id=1,r15.Name="Newcats",r15.UserId=null,r15.JoinTime=0001-01-01 00:00:00.000
