我使用Microsoft.SqlServer.Management.Smo备份数据库。我的问题是如何验证备份文件是否可恢复并且将正常工作。在互联网上花了一些时间后，我发现以下T-SQL验证但是在Microsoft.Management.Smo程序集中有一种方法。我期待一些代码示例。
RESTORE VERIFYONLY
FROM DISK = 'C:\Test\Test.bak'
WITH CHECKSUM
以下是我的代码示例。
using System;
using System.Configuration;
using System.Data.SqlClient;
using Microsoft.SqlServer.Management.Common;
using Microsoft.SqlServer.Management.Smo;
namespace BackupApplication
{
class DatabaseBackup
{
public void DoDataBaseBackup()
{
string connectionString = ConfigurationManager.ConnectionStrings["Test"].ToString();
SqlConnection connecton = new SqlConnection(connectionString);
ServerConnection serverConnection = new ServerConnection(connecton);
Server myServer = new Server(serverConnection);
//Using windows authentication
myServer.ConnectionContext.Connect();
Database myDatabase = myServer.Databases[ConfigurationManager.AppSettings["DatabaseNameToBackup"]];
//Backup operation
Backup bkpDBFull = new Backup();
/* Specify whether you want to back up database or files or log */
bkpDBFull.Action = BackupActionType.Database;
/* Specify the name of the database to back up */
bkpDBFull.Database = myDatabase.Name;
/* You can take backup on several media type (disk or tape), here I am
* using File type and storing backup on the file system */
string destinationFolderForDatabase = ConfigurationManager.AppSettings["DestinationFolderForDatabase"];
bkpDBFull.Devices.AddDevice(destinationFolderForDatabase, DeviceType.File);
bkpDBFull.BackupSetName = "Test database Backup";
bkpDBFull.BackupSetDescription = "test database - Full Backup";
/* You can specify the expiration date for your backup data
* after that date backup data would not be relevant */
bkpDBFull.ExpirationDate = DateTime.Today.AddDays(10);
/* You can specify Initialize = false (default) to create a new
* backup set which will be appended as last backup set on the media. You
* can specify Initialize = true to make the backup as first set on the
* medium and to overwrite any other existing backup sets if the all the
* backup sets have expired and specified backup set name matches with
* the name on the medium */
bkpDBFull.Initialize = false;
/* You can specify Incremental = false (default) to perform full backup or Incremental = true to perform differential backup since most recent full backup */
bkpDBFull.Incremental = false;
/* Wiring up events for progress monitoring */
bkpDBFull.PercentComplete += CompletionStatusInPercent;
bkpDBFull.Complete += Backup_Completed;
/* SqlBackup method starts to take back up
* You can also use SqlBackupAsync method to perform the backup
* operation asynchronously */
bkpDBFull.SqlBackup(myServer);
if (myServer.ConnectionContext.IsOpen)
{
myServer.ConnectionContext.Disconnect();
}
}
private void Backup_Completed(object sender, ServerMessageEventArgs e)
{
Console.WriteLine("TestDatabase Backup Completed.");
Console.WriteLine(e.Error.Message);
}
private void CompletionStatusInPercent(object sender, PercentCompleteEventArgs e)
{
Console.Clear();
Console.WriteLine("Percent completed: {0}%.", e.Percent);
}
}
}
Program.cs的
using System;
namespace BackupApplication
{
class Program
{
static void Main(string[] args)
{
DatabaseBackup databaseBackup = new DatabaseBackup();
databaseBackup.DoDataBaseBackup();
Console.ReadLine();
}
}
}
App.Config中
<connectionStrings>
<add name="TestDatabase" connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=Test;Integrated Security=SSPI"/>
</connectionStrings>
<appSettings>
<add key="DestinationFolderForDatabase" value="C:\Test.bak"/>
<add key="DatabaseNameToBackup" value="Test"/>
</appSettings>
