c#调用mssql视图生成xls文件地疑难?

string viewname = "ybxh20080819155449";//"ybxh" + DateTime.Now.ToString("yyyyMMddHHmmss");

        //view.createview(sqls, viewname);

        string sqls2 = "master..xp_cmdshell 'bcp  lmcs_cz.." + viewname + " out " + view.get_folder() + viewname + ".xls -c -q -S\".\" -U\"yzone\" -P\"112113\"\'";

        //view.xls(sqls2,1);

        SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["lmcs_czConnectionString"].ConnectionString);

        con.Open();

        SqlCommand cmd = new SqlCommand();

        cmd.CommandText = sqls2;

        cmd.Connection = con;

        cmd.ExecuteNonQuery();

        con.Close();
