Loop field with reflection in class and call a function on a interface

I'm trying to loop my IRepository field in my class XmlSerialization with the use of Reflection. I'm not able to define a IRepository in foreach loop instead i tried with var. But i can then not call IRepository.Save, Somehow i ned to filter the generic IRepository in the foreach loop.

The type arguments for method 'Fle.SQLServer.XmlFiles.Notifier.XmlSerialization.Save(Fle.SQLServer.Core.Services.IRepository)' cannot be inferred from the usage. Try specifying the type arguments explicitly.

I understand my problem but cant fix it.

I want to loop my IRepository fields on XmlSerialization and call save without calling each fields in the class.

using Fle.SQLServer.Core.Model;
using Fle.SQLServer.Core.Services;

namespace Fle.SQLServer.XmlFiles.Notifier
{
  public class XmlSerialization : INotifier
  {
    private readonly IRepository<BackupDeviceLocationData> _repositoryBackupDeviceLocation;
    private readonly IRepository<BackupHistoryData> _repositoryBackupHistory;
    private readonly IRepository<DatabaseSizesData> _repositoryDatabaseSizes;
    private readonly IRepository<DiskSystemData> _repositoryDiskSystem;
    private readonly IRepository<FailedDatabaseJobsData> _repositoryFailedDatabaseJobs;
    private readonly IRepository<DatabaseReplicationData> _repositoryDatabaseReplication;
    private readonly IRepository<DatabaseLongRunningJobData> _repositoryDatabaseLongRunningJob;
    private readonly IRepository<DatabaseSystemData> _repositoryDatabaseSystem;
    private readonly IRepository<DiskBackupData> _repositoryDiskBackup;
    private readonly IRepository<SqlServerAgentEventLogData> _repositorySqlServerAgentEventLog;
    private readonly IRepository<SqlServerEventLogData> _repositorySqlEventLog;
    private readonly IRepository<DatabaseOwnerData> _repositoryDatabaseOwner;
    private readonly IRepository<RecoveryModelData> _repositoryRecoveryModel;
    private readonly IRepository<BelongToSystemData> _repositoryBelongToSystem;

    public XmlSerialization(IRepository<BackupDeviceLocationData> repositoryBackupDeviceLocation,
      IRepository<BackupHistoryData> repositoryBackupHistory,
      IRepository<DatabaseSizesData> repositoryDatabaseSizes,
      IRepository<DiskSystemData> repositoryDiskSystem,
      IRepository<FailedDatabaseJobsData> repositoryFailedDatabaseJobs,
      IRepository<DatabaseReplicationData> repositoryDatabaseReplication,
      IRepository<DatabaseLongRunningJobData> repositoryDatabaseLongRunningJob,
      IRepository<DatabaseSystemData> repositoryDatabaseSystem,
      IRepository<DiskBackupData> repositoryDiskBackup,
      IRepository<SqlServerAgentEventLogData> repositorySqlServerAgentEventLog,
      IRepository<SqlServerEventLogData> repositorySqlEventLog,
      IRepository<DatabaseOwnerData> repositoryDatabaseOwner,
      IRepository<RecoveryModelData> repositoryRecoveryModel,
      IRepository<BelongToSystemData> repositoryBelongToSystem)
    {
      _repositoryBackupDeviceLocation = repositoryBackupDeviceLocation;
      _repositoryBackupHistory = repositoryBackupHistory;
      _repositoryDatabaseSizes = repositoryDatabaseSizes;
      _repositoryDiskSystem = repositoryDiskSystem;
      _repositoryFailedDatabaseJobs = repositoryFailedDatabaseJobs;
      _repositoryDatabaseReplication = repositoryDatabaseReplication;
      _repositoryDatabaseLongRunningJob = repositoryDatabaseLongRunningJob;
      _repositoryDatabaseSystem = repositoryDatabaseSystem;
      _repositoryDiskBackup = repositoryDiskBackup;
      _repositorySqlServerAgentEventLog = repositorySqlServerAgentEventLog;
      _repositorySqlEventLog = repositorySqlEventLog;
      _repositoryDatabaseOwner = repositoryDatabaseOwner;
      _repositoryRecoveryModel = repositoryRecoveryModel;
      _repositoryBelongToSystem = repositoryBelongToSystem;
    }


    public void Notify()
    {
      foreach (var field in this.GetType().GetProperties())
      {        
        field.Save();
      }       
    }      
  }
}
