如何使用Microsoft.SqlServer.Management.Smo命名空间的还原类进行还原

public void RestoreDatabase(String databaseName, String filePath, String serverName, String userName, String password, String dataFilePath, String logFilePath) { Restore sqlRestore = new Restore(); BackupDeviceItem deviceItem = new BackupDeviceItem(filePath, DeviceType.File); sqlRestore.Devices.Add(deviceItem); sqlRestore.Database = databaseName; ServerConnection connection = new ServerConnection(serverName, userName, password); Server sqlServer = new Server(connection); Database db = sqlServer.Databases[databaseName]; sqlRestore.Action = RestoreActionType.Database; String dataFileLocation = dataFilePath; String logFileLocation = logFilePath; db = sqlServer.Databases[databaseName]; sqlRestore.RelocateFiles.Add(new RelocateFile(databaseName, dataFileLocation)); sqlRestore.RelocateFiles.Add(new RelocateFile(databaseName + "_log", logFileLocation)); sqlRestore.ReplaceDatabase = true; sqlRestore.Complete +=new ServerMessageEventHandler(sqlRestore_Complete); sqlRestore.SqlRestore(sqlServer); db = sqlServer.Databases[databaseName]; db.SetOnline(); sqlServer.Refresh(); } 

在调用此方法时，还原操作因此消息而失败

服务器’MDM04 \ SQLEXPRESS’的恢复失败。

mdm04是我的电脑名称

内在的例外是

“System.Data.SqlClient.SqlError：逻辑文件’vrv’不是数据库’vrv’的一部分。使用RESTORE FILELISTONLY列出逻辑文件名。”

vrv是数据库名称

我该怎么做才能恢复文件

Answer 1

问题在这里

 sqlRestore.RelocateFiles.Add(new RelocateFile(databaseName, dataFileLocation)); sqlRestore.RelocateFiles.Add(new RelocateFile(databaseName + "_log", logFileLocation)); 

这里databaseName表示db备份文件中指定的数据库的名称。 但是您要指定目标数据库名称。

将其更改为原始数据库名称

这里是从备份文件中读取db名称的示例代码

 DataTable dtFileList = sqlRestore.ReadFileList(serverName); string dbLogicalName = dtFileList.Rows[0][0].ToString(); string dbPhysicalName = dtFileList.Rows[0][1].ToString(); string logLogicalName = dtFileList.Rows[1][0].ToString(); string logPhysicalName = dtFileList.Rows[1][1].ToString 

Answer 2

现在转到“浏览”标签，浏览以下路径 –

C：\ Program Files \ Microsoft SQL Server \ 100 \ SDK \ Assemblies OR C：\ Program Files \ Microsoft SQL Server \ 110 \ SDK \ Assemblies

现在选择以下dll

Microsoft.SqlServer.ConnectionInfo.dll

Microsoft.SqlServer.Management.Sdk.Sfc.dll

Microsoft.SqlServer.Smo.dll

Microsoft.SqlServer.SmoExtended.dll

Microsoft.SqlServer.SqlEnum.dll

  public void RestoreDatabase(String databaseName, String filePath, String serverName, String userName, String password, String dataFilePath, String logFilePath) { Restore sqlRestore = new Restore(); BackupDeviceItem deviceItem = new BackupDeviceItem(filePath, DeviceType.File); sqlRestore.Devices.Add(deviceItem); sqlRestore.Database = databaseName; ServerConnection connection = new ServerConnection(serverName, userName, password); Server sqlServer = new Server(connection); Database db = sqlServer.Databases[databaseName]; sqlRestore.Action = RestoreActionType.Database; String dataFileLocation = dataFilePath; String logFileLocation = logFilePath; db = sqlServer.Databases[databaseName]; sqlRestore.RelocateFiles.Add(new RelocateFile(databaseName, dataFileLocation)); sqlRestore.RelocateFiles.Add(new RelocateFile(databaseName + "_log", logFileLocation)); sqlRestore.ReplaceDatabase = true; sqlRestore.Complete +=new ServerMessageEventHandler(sqlRestore_Complete); sqlRestore.SqlRestore(sqlServer); db = sqlServer.Databases[databaseName]; db.SetOnline(); sqlServer.Refresh(); }
