求急????
wApp.Selection.TypeText(BusinessLogic.PublicEnum.GetEnumDescription (System.Enum.Parse(typeof(BusinessEntity.DocumentType), sdr[ "HolderDocumentType "].ToString().Replace( "HolderDocumentType ", " "))));
值是-1我把-1替换为空 为什么还是显示-1呢,我试过好多次.枚举替换怎么替换啊,也是一样吗?
wApp.Selection.TypeText(BusinessLogic.PublicEnum.GetEnumDescription (System.Enum.Parse(typeof(BusinessEntity.DocumentType), sdr[ "HolderDocumentType "].ToString().Replace( "-1 ", " "))));
这样做也不行
wApp.Selection.TypeText(BusinessLogic.PublicEnum.GetEnumDescription (System.Enum.Parse(typeof(BusinessEntity.DocumentType), sdr[ "DocumentType "].ToString().Replace( "DocumentType ", " "))));
这样也不行
也不可能是空值啊,都是显示-1
------解决方案--------------------数据库中一样。默认值是 -1
------解决方案--------------------sdr 是 SqlDataReader ?
请你输出 sdr[ "HolderDocumentType "].ToString() 是什么?
sdr[ "HolderDocumentType "].ToString() 中包含 "HolderDocumentType " 吗?
比较好的方式是,数据库中存储枚举值,而不是名称,such as
BusinessEntity.DocumentType docType = (BusinessEntity.DocumentType)((int)sdr[ "HolderDocumentType "]); // 这里假设 BusinessEntity.DocumentType 的基元类型是 int
