我不知道这个错误是什么意思。我使用的是 Visual Studio for Mac 7.5.0 社区版。我在带有 ASP.NET Core 的 Entity Framework 中使用延迟加载。
public partial class AdminUser
{
public AdminUser()
{
RoleAssign = new HashSet<RoleAssign>();
}
public Guid UserId { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string Email { get; set; }
public string UserName { get; set; }
public byte[] Password { get; set; }
public DateTime CreatedTimeStamp { get; set; }
public DateTime? ModifiedTimeStamp { get; set; }
public DateTime? LogDate { get; set; }
public short? LogNumber { get; set; }
public bool ReloadActiveFlag { get; set; }
public bool IsActive { get; set; }
public string ExtraText { get; set; }
public string ResetPasswordToken { get; set; }
public DateTime? ResetPasswordTokenCreatedTimeStamp { get; set; }
public virtual ICollection<RoleAssign> RoleAssign { get; set; }
}
RoleAssign
实体模型:
public partial class RoleAssign
{
public Guid RoleAssignId { get; set; }
public Guid RoleId { get; set; }
public Guid UserId { get; set; }
public virtual AdminRole Role { get; set; }
public virtual AdminUser User { get; set; }
}
这是实体构建器:
modelBuilder.Entity<RoleAssign>(entity =>
{
entity.Property(e => e.RoleAssignId).ValueGeneratedNever();
entity.HasOne(d => d.Role)
.WithMany(p => p.RoleAssign)
.HasForeignKey(d => d.RoleId)
.OnDelete(DeleteBehavior.ClientSetNull)
.HasConstraintName("FK__RoleAssig__RoleI__160F4887");
entity.HasOne(d => d.User)
.WithMany(p => p.RoleAssign)
.HasForeignKey(d => d.UserId)
.OnDelete(DeleteBehavior.ClientSetNull)
.HasConstraintName("FK__RoleAssig__UserI__17036CC0");
});
这是用户表的实体构建器:
modelBuilder.Entity<AdminUser>(entity =>
{
entity.HasKey(e => e.UserId);
entity.Property(e => e.UserId).ValueGeneratedNever();
entity.Property(e => e.CreatedTimeStamp)
.HasColumnType("datetime")
.HasDefaultValueSql("(getdate())");
entity.Property(e => e.Email)
.IsRequired()
.IsUnicode(false);
entity.Property(e => e.ExtraText).IsUnicode(false);
entity.Property(e => e.FirstName)
.IsRequired()
.IsUnicode(false);
entity.Property(e => e.IsActive)
.IsRequired()
.HasColumnName("isActive")
.HasDefaultValueSql("((1))");
entity.Property(e => e.LastName)
.IsRequired()
.IsUnicode(false);
entity.Property(e => e.LogDate).HasColumnType("datetime");
entity.Property(e => e.ModifiedTimeStamp).HasColumnType("datetime");
entity.Property(e => e.Password).IsRequired();
entity.Property(e => e.ResetPasswordToken).IsUnicode(false);
entity.Property(e => e.ResetPasswordTokenCreatedTimeStamp).HasColumnType("datetime");
entity.Property(e => e.UserName)
.IsRequired()
.IsUnicode(false);
});
UOW 代码:
public async Task<UserViewModel> AdminAuthentication(UserViewModel userView)
{
var user = await _adminGenericRepository.FindAsync(x => x.IsActive && x.UserName.Equals(userView.UserName) && (AesEncryptAndDecrypt.DecryptStringFromBytes(x.Password, crytograpyKey, crytograpyIV).Equals(userView.Password)));
if (user != null)
{
return new UserViewModel
{
UserId = user.UserId,
isActive = user.IsActive,
UserName = user.UserName,
LastName = user.LastName,
FirstName = user.FirstName,
SelectedRole = mapRoleDbDataToViewModel(user.RoleAssign != null ? user.RoleAssign.FirstOrDefault().Role : null)
};
}
return null;
}
映射器类:
private RoleViewModel mapRoleDbDataToViewModel(AdminRole dbRole)
{
if (dbRole != null)
{
return new RoleViewModel
{
RoleId = dbRole.RoleId,
RoleName = dbRole.RoleName,
RoleType = dbRole.RoleType,
SortOrder = dbRole.SortOrder,
TreeLevel = dbRole.TreeLevel,
Permissions = GetRuleByRoleId(dbRole.RoleId)
};
}
return null;
}
存储库文件:
public virtual async Task<T> FindAsync(Expression<Func<T, bool>> predicate)
{
return await _entities.Set<T>().SingleOrDefaultAsync(predicate);
}
public IQueryable<T> FindBy(System.Linq.Expressions.Expression<Func<T, bool>> predicate)
{
IQueryable<T> query = _entities.Set<T>().Where(predicate);
return query;
}
错误信息截图:
成绩单:
Inspecting the state of an object in the debuggee of type System.Reflection.MethodBase is not supported in this context.
最佳答案
根据我对你的理解,调试发生在 Visual Studio 调试器的表达式电梯中,因此这可能意味着调试器试图从 System.Reflection.MethodBase 类型的实例中获取数据,但此类对象不可用,所以它产生了那个错误,
您可以尝试使用旧版调试引擎,可能会修复它 (工具 -> 选项 -> 调试 -> 常规 -> “使用托管兼容模式”)
