C#实现SqlServer的数据库和还原

要实现数据库的还原，需要数据库在没有使用的情况下才能进行数据库的还原，所以在本例中通过在master数据库中创建一个杀死数据库进程的存储过程，传入参数为数据库名称，存储过程名称代码如下：

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#实现数据库的备份代码：

  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#实现数据库的还原代码：

        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;
        }
