Newcats.Utils 使用说明
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
Newcats.Utils.Models.EnumDescription r5 = Season.Spring.GetEnumDescription();//=>r5.Value=0,r5.Name="Spring",r5.Description="春季"
//10.获取枚举的所有枚举描述类
List<Newcats.Utils.Models.EnumDescription> r6 = Season.Spring.GetAllEnumDescriptions();//=>r6[0].Value=1,r6[0].Name="Spring"...r6[1].Value=1,r6[2].Description="夏季"

//33.RSA私钥解密
string r29 = Newcats.Utils.Helpers.EncryptHelper.RsaDecrypt(r28);
//34.RSA签名
string r30 = Newcats.Utils.Helpers.EncryptHelper.RsaSignData("Newcats");
//41.RSA验签
bool r31 = Newcats.Utils.Helpers.EncryptHelper.RsaVerifyData("Newcats", r30);//=>bool
//42.生成RSA密钥
RsaKey r32 = Newcats.Utils.Helpers.EncryptHelper.CreateRsaKey(RsaKeyFormatEnum.Pkcs8, 4096, true);
