我有这个模型类：

using StackExchange.Redis;
using System;
using System.Collections.Generic;
using Ucdp.Common.Enums.Vendor;

namespace Ucdp.Common.Industry
{
    public class VendorBasicDetailsByChannelModel
    {
        public Guid Id { get; set; }
        public string Name { get; set; }
        public VendorMode VendorMode { get; set; }
    }
}

在模型中，一个字段（VendorMode）具有ENUM模型（VendorMode）。
enum模型有4个enum类型

using System;
using System.Collections.Generic;
using System.Text;

namespace Ucdp.Common.Enums.Vendor
{
    public enum VendorMode
    {
        Shopping = 1,
        Discovery = 2,
        ShoppingAndDiscovery = 3
    }

   
}

and this is vendor.proto file

syntax = "proto3";

option csharp_namespace = "IndustryAPI.Protos";

import "google/protobuf/wrappers.proto";

message ListOfStrings {
    repeated string strings = 1;
}

enum VendorMode {
  VendorMode_UNSPECIFIED = 0;
  Shopping = 1;
  Discovery = 2;
  ShoppingAndDiscovery = 3;
}

message VendorModel {
    string Id = 1;
    string Name = 2;
    VendorMode VendorMode = 3;
}

service VendorService {
    rpc GetVendorBasicDetails(GetVendorBasicDetailsRequest) returns (GetVendorBasicDetailsResponse);
}

// requests
message GetVendorBasicDetailsRequest {
    string channelId = 1;
    string VendorCreatedDateStart = 2;
    string VendorCreatedDateEnd = 3;
}

message GetVendorBasicDetailsResponse {
    repeated VendorModel Vendor = 1;
}

I want to map each field with message
var Vendor = new VendorModel
                    {
                        Id = vendor.Id.ToString(),
                        Name = vendor.Name,
                        VendorMode = vendor.VendorMode
                    };

如何Map枚举？
