mysql二进制对应ef中实体表字段类型

1、ef中设计成byte[],如下：

    /// <summary>
    /// 会员证
    /// </summary>
    public class MemberCard : AuditedEntity<Guid>
    {
        /// <summary>
        /// 企业id
        /// </summary>
        public Guid CompanyId { get; set; }

        /// <summary>
        /// 图片地址
        /// </summary>
        public byte[] ImgUrl { get; set; }
    }

使用abp中的dotnet ef migrations add AddTable_MemberCard

生成如下longblob类型：

ImgUrl = table.Column<byte[]>(type: "longblob", nullable: false, comment: "证书图片url"),

using System;
using Microsoft.EntityFrameworkCore.Migrations;

#nullable disable

namespace BaseService.Migrations
{
    /// <inheritdoc />
    public partial class AddTableMemberCard : Migration
    {
