我正在尝试使用 Entity Framework 从数据库中读取记录,这是我以前没有使用过的。
我试图运行加载规则方法:
class Rule
{
private STRATCODE stratCode;
private STRATRULEDEF stratRuleDef;
AREEntities AREDb = new AREEntities();
public Rule(STRATRULEDEF StratRuleDef, STRATCODE StratCode)
{
this.stratRuleDef = StratRuleDef;
this.stratCode = StratCode;
}
public void LoadRule()
{
var query = from stratCode in AREDb.STRATCODES
where stratCode.CODEVALUE == "49300"
select stratCode;
//StratCodeRepository StratCodeRepository = new StratCodeRepository(new AREEntities());
using (System.IO.StreamWriter file = new System.IO.StreamWriter(@"C:\Users\user\Desktop\NewText.txt",true))
{
foreach (STRATCODE row in query)
{
file.WriteLine("{0} | {1} | {2} | {3} | {4} | {5}", stratCode.STRATRULEKEY, stratCode.CODETYPE, stratCode.CODEVALUE, stratCode.SYSTEMID, stratCode.CODESETKEY, stratCode.PAYMENTYEAR);
}
}
}
我的问题是,每次我运行它时,它都会返回正确数量的记录,但文本文件中的所有数据都是空的,我在输出日志中找不到任何线索。
0 | | | | |

有任何想法吗?我什至不知道如何在没有线索的情况下开始
