如何在C＃中恢复数据库SQL 2008？

Question

I want to restore database in C#, use file type .BAK

var db = new QLTDEntities();
var con = ((SqlConnection)db.Database.Connection);
con.Open();
string stringquery = "RESTORE DATABASE TEST FROM DISK ='D:\ABC.BAK'";
SqlCommand cmd = new SqlCommand(stringquery, con);
cmd.ExecuteNonQuery();
con.Close();

I get error at line cmd.ExecuteNonQuery();

'TEST' is not a recognized RESTORE option.

Can you tell me what i mistake or wrong place.?

Answer 1

试试这样：

string stringquery = @"USE master BACKUP DATABASE [TEST] TO DISK='D:\ABC.BAK'";

Answer 2

You need to connect to the master database, and then you can restore your database.
