smo恢復數據庫

Question

我使用SQL Server SMO將.bak恢復到新數據庫，但失敗。

的SQL Server 2012是和SMO對象版本是最新的SDK版本11.0

.bak的文件是使用SQL管理工作室2012年，同樣的本地PC，在相同的編碼PC以及創建。

該錯誤消息我得到的是：

還原失敗的服務器 '服務器'。

我的代碼有什麼問題？

string dbPath = Path.Combine(@"d:\my data", dbName + "_db" + ".mdf"); 
string logPath = Path.Combine(@"d:\my data", dbName + "_db" + "_Log.ldf"); 

Restore restore = new Restore(); 

BackupDeviceItem deviceItem = new BackupDeviceItem("d:\template.BAK", DeviceType.File); 
restore.Devices.Add(deviceItem); 
restore.Database = dbName + "_db"; 

RelocateFile relocateDataFile = new RelocateFile("Data", dbPath); 
RelocateFile relocateLogFile = new RelocateFile("Log", logPath); 

restore.RelocateFiles.Add(relocateDataFile); 
restore.RelocateFiles.Add(relocateLogFile); 

restore.Action = RestoreActionType.Database; 
restore.ReplaceDatabase = true; 
restore.SqlRestore(server); 

更新：我surrended SMO解決方案，並試圖

using (SqlConnection connection = new SqlConnection("Data Source=server;user id=sa;password=xxxxx;")) 
     { 

      using (SqlCommand command = new SqlCommand(@"RESTORE DATABASE beauty01 FROM DISK = 'd:\template.bak' WITH RECOVERY, MOVE 'beauty1' TO 'D:\MyData\beauty01_Data.mdf', MOVE 'beauty1_log' TO 'd:\Mydata\beauty01_Log.ldf', REPLACE", connection)) 
      { 
       connection.Open(); 
       // Add the parameters for the SelectCommand. 


       command.CommandType = CommandType.Text; 
       command.ExecuteNonQuery(); 
      } 

     } >> work good. 

感謝所有。

我成功地使用了SMO來恢復數據庫。我會分享我的代碼。希望能幫助到你。這個解決方案雖然有一個警告，但它認爲你只有一個主數據文件。使日誌和數據文件相匹配非常棘手，在許多方面可能會出現問題。無論如何，儘量讓我知道這有助於。
