我可以使用以下方法在硬盘上备份数据库：

void BackUp(string ConnectionString, string DatabaseFullPath, string backUpPath)
{
    progressBar1.Value = 0;

    using (SqlConnection con = new SqlConnection(ConnectionString))
    {
        con.Open();

        string UseMaster = "USE master";
        SqlCommand UseMasterCommand = new SqlCommand(UseMaster, con);
        UseMasterCommand.ExecuteNonQuery();

        progressBar1.Value += 25;

        string Alter1 = @"ALTER DATABASE [" + DatabaseFullPath + "] SET Single_User WITH Rollback Immediate";
        SqlCommand Alter1Cmd = new SqlCommand(Alter1, con);
        Alter1Cmd.ExecuteNonQuery();

        progressBar1.Value += 25;

        string Restore = @"BACKUP DATABASE [" + DatabaseFullPath + "] TO  DISK = N'" + backUpPath + @"' WITH NOFORMAT, NOINIT,  NAME = N'" + DatabaseFullPath + "-Full Database Backup', SKIP, NOREWIND, NOUNLOAD,  STATS = 10";
        SqlCommand RestoreCmd = new SqlCommand(Restore, con);
        RestoreCmd.ExecuteNonQuery();

        progressBar1.Value += 25;

        string Alter2 = @"ALTER DATABASE [" + DatabaseFullPath + "] SET Multi_User";
        SqlCommand Alter2Cmd = new SqlCommand(Alter2, con);
        Alter2Cmd.ExecuteNonQuery();

        progressBar1.Value += 25;

        labelReport.Text = "Successful";
    }
}

并且，如何将其转换为存储过程？

如果您的意图是将备份任务完全封装在存储过程中以便可以从 C# 中执行，那么您是否想考虑使用SQL Server 管理对象(SMO)？这些对象使您能够以编程方式访问 SQL Server 管理任务，例如执行备份。在此处查看第二个示例：http: //msdn.microsoft.com/en-us/library/ms162133.aspx

编辑：但要回答这个问题，你可以按照这个对我有用的例子：

CREATE PROCEDURE BackupDatabase
(
    @databaseName sysname, 
    @backupPath varchar(260)
)
AS
BEGIN
    BACKUP DATABASE @databaseName 
        TO DISK = @backupPath
        WITH FORMAT;
END
GO

由

DECLARE @return_value int

EXEC    @return_value = [dbo].[BackupDatabase]
        @databaseName = play,
        @backupPath = N'c:\backup\play.bak'

SELECT  'Return Value' = @return_value

GO
