检查重复项

Question

我正在使用以下代码，该代码无法检查“修订状态”

的重复值

private bool CheckRevision(string docType,string Revision)
        {
            bool Res = false;
            DataTable DT = new DataTable();
            DT = PinDicDAO.GetRevision(docType);
            DataView DV = new DataView(DT);
            DV.RowFilter = "RevisionStatus='" + Revision.Replace(" ", "") + "' OR RevisionStatus='"+Revision+"'";
            if (DV.Count > 0)
                Res = true;

            return Res;
        }

RevStatus的

格式就像

CN - Cancelled
IFP - Issued For Purchase

Answer 1

尝试检查数据表。

if (DT.Rows.Count > 0)
                Res = true;

            return Res;
