C#實現SqlServer的數據庫和還原

要實現數據庫的還原，需要數據庫在沒有使用的情況下才能進行數據庫的還原，所以在本例中通過在master數據庫中創建一個殺死數據庫進程的存儲過程，傳入參數為數據庫名稱，存儲過程名稱代碼如下：

create proc p_killspid 
 @dbname sysname 
 as 
 declare @s nvarchar(1000) 
 declare tb cursor local for 
 select s='kill '+cast(spid as varchar) 
 from master..sysprocesses 
 where dbid=db_id(@dbname) 
 
 open tb 
 fetch next from tb into @s 
 while @@fetch_status=0 
 begin 
 exec(@s) 
 fetch next from tb into @s 
 end 
 close tb 
 deallocate tb 
go 

C#實現數據庫的備份代碼：

  public bool Backup(string fileName,string dataBaseName)
        {
            string backUpSql = string.Format("use master;backup database {0} to disk = '{1}';", dataBaseName, fileName);
            return this.m_DataAccess.ExecuteNonQuery(backUpSql) >= 0 ? true : false;
        }

C#實現數據庫的還原代碼：

        public bool Restore(string fileName,string dataBaseName)
        {
            string restoreSql = string.Format("use master;exec p_killspid '{0}';restore database {0} From disk = '{1}' with replace;", dataBaseName, fileName);
            return this.m_DataAccess.ExecuteNonQuery(restoreSql) >= 0 ? true : false;
        }
