C# 还原SQL数据库(非存储过程方式)

Winform的代码,最好是在数据所在电脑上运行代码,不然会因为权限问题导致失败。

数据库备份:

            SqlConnection con = new SqlConnection("Data Source=.;;Initial Catalog=DB_Test;User ID=sa;Password=sa");            string sql = "backup database DB_Test to disk= ‘c:\\aVb.bak‘";            con.Open();            if (!File.Exists("c:\\aa.bak"))            {                SqlCommand com = new SqlCommand(sql, con);                com.ExecuteNonQuery();      //执行sql语句                   lblmessage.Text = "系统信息:备份成功!";            }            else            {                lblmessage.Text = "系统信息:文件已存在!";            } 

 

数据库还原:

            //引用SQLDMO.dll,SQLDMO由Microsoft   SQL   Server自带的SQLDMO.dll提供,SQLDMO.dll是一个COM对象            SQLDMO.SQLServer svr = new SQLDMO.SQLServerClass();            try            {                svr.Connect("192.168.89.20", "sa", "Aa123456");                //取得所有的进程列表                SQLDMO.QueryResults qr = svr.EnumProcesses(-1);                int iColPIDNum = -1;                int iColDbName = -1;                //找到和要恢复数据库相关的进程                for (int i = 1; i <= qr.Columns; i++)                {                    string strName = qr.get_ColumnName(i);                    if (strName.ToUpper().Trim() == "SPID")                    {                        iColPIDNum = i;                    }                    else if (strName.ToUpper().Trim() == "DBNAME")                    {                        iColDbName = i;                    }                    if (iColPIDNum != -1 && iColDbName != -1)                        break;                }                //将相关进程杀死                for (int i = 1; i <= qr.Rows; i++)                {                    int lPID = qr.GetColumnLong(i, iColPIDNum);                    string strDBName = qr.GetColumnString(i, iColDbName);                    if (strDBName.ToUpper() == strDbName.ToUpper())                        svr.KillProcess(lPID);                }                SQLDMO.Restore res = new SQLDMO.RestoreClass();                res.Action = SQLDMO.SQLDMO_RESTORE_TYPE.SQLDMORestore_Database;                res.Files = strFileName;                res.Database = strDbName;                res.FileNumber = 1;                res.ReplaceDatabase = true;                res.SQLRestore(svr);                return true;            }            catch (Exception err)            {                //throw (new Exception("" + err.Message));               MessageBox.Show("恢复数据库失败,请关闭所有和该数据库连接的程序!" + err.Message);                return false;            }            finally            {                svr.DisConnect();            }
