我看到的问题是这行中的关键字
值 foreach (TblSample rec in LstTblSample)
{
OleDbCommand cmdInsert = new OleDbCommand("insert into [sd$]" +
"([Lab Ref],[D.M.],PH,CP,ADF,NDF,DMD,ME,NIRASH,IFCOW,IFSHEEP,NH3,UFV,UFL,PDIE,PDIN,PDIA,LFU,CFU,SFU) values" +

cmdInsert.ExecuteNonQuery();
}
OleDbCommand cmdInsert = new OleDbCommand("insert into [sd$] values" +
值之前指定列字段。或者，您可以调用值
，而无需命名列字段。在这种情况下，两者都可以。在指定列之前，上面的值会导致问题
foreach (TblSample rec in LstTblSample)
{
OleDbCommand cmdInsert = new OleDbCommand("insert into [sd$]" +
"([Lab Ref],[D.M.],PH,CP,ADF,NDF,DMD,ME,NIRASH,IFCOW,IFSHEEP,NH3,UFV,UFL,PDIE,PDIN,PDIA,LFU,CFU,SFU) values" +

"'" + rec.CrudeProtein + "'" + "," + "'" + "" + "'" + "," + "'" + rec.NDF + "'" + "," + "'" + rec.DMD + "'" + "," +
"'" + rec.ME + "'" + "," + "'" + rec.ASH + "'" + "," + "'" + rec.DMIntakeCattle + "'" + "," +

cmdInsert.ExecuteNonQuery();
}
一个选项是完全删除列声明，只需将插入[sd$]值”（“+”““+rec.SampleNo+
）-即，列和条目是否匹配。您还可以尝试将insert语句中的列重命名为[DM]然后在插入数据后，将excel电子表格中的列重命名为[D.M.]，作为例行任务，使用以下代码对其进行修改：
foreach (TblSample rec in LstTblSample)
{
OleDbCommand cmdInsert = new OleDbCommand("insert into [sd$]" +
"([Lab Ref],[D.M.],PH,CP,ADF,NDF,DMD,ME,NIRASH,IFCOW,IFSHEEP,NH3,UFV,UFL,PDIE,PDIN,PDIA,LFU,CFU,SFU) values" +
"(" + "'" + rec.SampleNo + "'" + "," + "'" + rec.DryMatter + "'" + "," + "'" + rec.pH + "'" + "," +
"'" + rec.CrudeProtein + "'" + "," + "'" + "" + "'" + "," + "'" + rec.NDF + "'" + "," + "'" + rec.DMD + "'" + "," +
"'" + rec.ME + "'" + "," + "'" + rec.ASH + "'" + "," + "'" + rec.DMIntakeCattle + "'" + "," +
"'" + rec.DMIntakeSheep + "'" + "," + "'" + rec.NH3 + "'" + "," + "'" + rec.UFV + "'" + "," +
"'" + rec.UFL + "'" + "," + "'" + rec.PDIE + "'" + "," + "'" + rec.PDIN + "'" + "," + "'" + rec.PDIA + "'" + "," +
"'" + rec.LFU + "'" + "," + "'" + rec.CFU + "'" + "," + "'" + rec.SFU + "'" + ")", con);
cmdInsert.ExecuteNonQuery();
}
如果所有其他操作都失败，请使用尝试操作文档
foreach (TblSample rec in LstTblSample)
{
OleDbCommand cmdInsert = new OleDbCommand("insert into [sd$]" +
"([Lab Ref],[D.M.],PH,CP,ADF,NDF,DMD,ME,NIRASH,IFCOW,IFSHEEP,NH3,UFV,UFL,PDIE,PDIN,PDIA,LFU,CFU,SFU) values" +
"(" + "'" + rec.SampleNo + "'" + "," + "'" + rec.DryMatter + "'" + "," + "'" + rec.pH + "'" + "," +
"'" + rec.CrudeProtein + "'" + "," + "'" + "" + "'" + "," + "'" + rec.NDF + "'" + "," + "'" + rec.DMD + "'" + "," +
"'" + rec.ME + "'" + "," + "'" + rec.ASH + "'" + "," + "'" + rec.DMIntakeCattle + "'" + "," +
"'" + rec.DMIntakeSheep + "'" + "," + "'" + rec.NH3 + "'" + "," + "'" + rec.UFV + "'" + "," +
"'" + rec.UFL + "'" + "," + "'" + rec.PDIE + "'" + "," + "'" + rec.PDIN + "'" + "," + "'" + rec.PDIA + "'" + "," +
"'" + rec.LFU + "'" + "," + "'" + rec.CFU + "'" + "," + "'" + rec.SFU + "'" + ")", con);
cmdInsert.ExecuteNonQuery();
}
我退出了！祝你好运。对不起，这是我的复制粘贴中的一个错误。我在实际应用程序中正确地看到了这一点。我仍然会遇到这个错误
