SQL Server備份和從C＃問題

恢復我在C＃編寫的程序使用SQL 2008SQL Server備份和從C＃問題

我要備份的數據庫，並恢復它。我的備份代碼正常工作，但恢復不起作用，數據庫變成單個用戶。

收到以下錯誤：

日誌的尾部數據庫「醫生」還沒有被備份。使用備份日誌與NORECOVERY備份日誌如果它包含工作，你不想想要失去。使用WITH REPLACE或 WITH RESTORE 語句的STOPAT子句僅覆蓋日誌的內容。 RESTORE DATABASE 正在異常終止。不合格交易正在回滾。估計回滾

我的代碼：

private void Backup(string strFileName) 
{ 
    try 
    { 
     string command = @"BACKUP DATABASE doctor TO DISK='"+ strFileName+"'"; 
     SqlCommand oCommand = null; 
     SqlConnection oConnection = null; 
     oConnection = new SqlConnection("Data Source=.;Initial Catalog=doctor;Integrated Security=True"); 
     if (oConnection.State != ConnectionState.Open) 
     oConnection.Open(); 
     oCommand = new SqlCommand(command, oConnection); 
     oCommand.ExecuteNonQuery(); 


    } 
    catch (Exception ex) 
    { 
     MessageBox.Show(ex.Message); 
    } 
} 

private void Restore(string strFileName) 
{ 
    try 
    { 
     string command = "ALTER DATABASE doctor SET SINGLE_USER with ROLLBACK IMMEDIATE " + "use master " + " RESTORE DATABASE doctor FROM DISK='" + strFileName + "'"; 
     SqlCommand oCommand = null; 
     SqlConnection oConnection = null; 
     oConnection = new SqlConnection("Data Source=.;Initial Catalog=doctor;Integrated Security=True"); 
     if (oConnection.State == ConnectionState.Closed) 
     { 
      oConnection.Open(); 
      oCommand = new SqlCommand(command, oConnection); 
      oCommand.ExecuteNonQuery();    
     } 
    } 
    catch (Exception ex) 
    { 
     MessageBox.Show(ex.Message); 
    } 
}
