convert enums in Protobuf to enums in c#

Question

I have this proto file

syntax = "proto3";

message AdminIpoChange
{
 string Id =1;
 string SymbolName =2;
 string SymbolIsin =3;
 string Date =4;
 string Time=5;
 double MinPrice =6;
 double MaxPrice =7;
 int32 Share =8;
 bool Show =9;
 AdminIpoOperation Operation =10;
 string  CreateDateTime=11;
enum AdminIpoOperation
{
    Add = 0;
    Edit = 1;
    Delete = 2;
}

}

And here I have this class

 public class AdminIpoChangeEntity : BaseEntity
    {
        public AdminIpoChangeEntity()
        {

        }
        public string SymbolName { get; set; }
        public string SymbolIsin { get; set; }
        public string Date { get; set; }
        public string Time { get; set; }
        public double MinPrice { get; set; }
        public double MaxPrice { get; set; }
        public int Share { get; set; }
        public bool Show { get; set; }
        public AdminIpoOperation Operation { get; set; }
        public DateTime CreateDateTime { get; set; }



        public enum AdminIpoOperation
        {
            Add = 0,
            Edit = 1,
            Delete = 2
        }
}

So I want to convert the operation enum in proto to enum in c# as you can see :

        public static AdminIpoChangeEntity Map(AdminIpoChange adminIpoChange)
 => new()
 {
     
     CreateDateTime=DateTime.Parse(adminIpoChange.CreateDateTime),Date=adminIpoChange.Date,MaxPrice=adminIpoChange.MaxPrice,    
     MinPrice=adminIpoChange.MinPrice,Operation=adminIpoChange.Operation,Share=adminIpoChange.Share,Show=adminIpoChange.Show,
     SymbolIsin=adminIpoChange.SymbolIsin,SymbolName=adminIpoChange.SymbolName,Time=adminIpoChange.Time,
 };

But in this part Operation=adminIpoChange.OperationI get this error :

Severity    Code    Description Project File    Line    Suppression State
