[JsonConverter(typeof(StringEnumConverter))]

public enum
RecipientStatus
{
Sent,
Delivered,
Signed,
Declined
}
public class
RecipientsInfoDepartResult
{
[JsonConverter(typeof(StringEnumConverter))]
//属性将枚举转换为string
public RecipientStatus status {
set; get; }
public PositionBeanResult PredefineSign {

}

eg : public static
string GetName(Type enumType,Object value)
public static string[] GetNames(Type enumType)

Enum.GetName(typeof(Colors),3))与Enum.GetName(typeof(Colors),
Colors.Blue))的值都是"Blue"
Enum.GetNames(typeof(Colors))将返回枚举字符串数组

ty.ToString();

public static Object Parse(Type enumType,string value)
eg : (Colors)Enum.Parse(typeof(Colors), "Red");
(T)Enum.Parse(typeof(T),
strType)

protected static
T GetType<T>(string strType)
{
T t = (T)Enum.Parse(typeof(T),
strType);
return t;
}

RecipientStatus type = 
RecipientStatus.Sent;
Enum.IsDefined(typeof(RecipientStatus),
type );
