我想取得某個Field類型: dbgrid1.Columns[0].Field.FieldType; 但是卻編譯錯誤,為什么?有什么方法呢?

試試看：    DBGrid1.Columns.Items[0].Field.DataType; 可以得到以下的結果： {ftUnknown, ftString, ftSmallint, ftInteger, ftWord, ftBoolean, ftFloat, ftCurrency, ftBCD, ftDate, ftTime, ftDateTime, ftBytes, ftVarBytes, ftAutoInc, ftBlob, ftMemo, ftGraphic, ftFmtMemo, ftParadoxOle, ftDBaseOle, ftTypedBinary, ftCursor ftFixedChar, ftWideString, ftLargeint, ftADT, ftArray, ftReference, ftDataSet, ftOraBlob, ftOraClob, ftVariant, ftInterface, ftIDispatch, ftGuid, ftTimeStamp, ftFMTBcd} or DBGrid1.Columns.Items[0].Field.FieldKind; 可以得到以下的結果： {fkData, fkCalculated, fkLookup, fkInternalCalc, fkAggregate} 不曉得你要的是哪一種 發表人 - allenchan 於 2004/12/04 11:35:08

    var i:integer;
begin
  for i:= 0 to dbgrid1.DataSource.dataset.FieldDefs.count-1 do begin
    if dbgrid1.Columns[0].field.fieldname
      =dbgrid1.DataSource.dataset.FieldDefs.items[i].name
    then begin
       showmessage(dbgrid1.DataSource.dataset.FieldDefs.items[i].fieldclass.classname);
       break;
    end;
  end;
end;
