devexpress xtragrid使用循环以编程方式创建

我使用带有高级带状网格视图的devexpress xtragrid。网格将在运行时以编程方式创建。我写的代码，它的工作。但是现在我需要用一个循环来创建网格，我的意思是我不知道列号，这取决于用户

这是我的第一个代码（成功了）：

循环一（它不工作）：

DevExpress.XtraGrid.Views.bandegrid.GridBand[]GridBand=new-DevExpress.XtraGrid.Views.bandegrid.GridBand[2]；
对于（int i=0；i<2；i++）
{
gridBand[i]=new DevExpress.XtraGrid.Views.bandegrid.gridBand（）；
DevExpress.XtraGrid.Views.bandegrid.bandegridColumn colTrademark=新建DevExpress.XtraGrid.Views.bandegrid.bandegridColumn（）；
DevExpress.XtraGrid.Views.bandegrid.bandegridColumn colModel=新建DevExpress.XtraGrid.Views.bandegrid.bandegridColumn（）；
colTrademark.Caption=“商标”+i.ToString（）；
colTrademark.FieldName=“商标”+i.ToString（）；
colTrademark.Name=“colTrademark”+i.ToString（）；
colTrademark.SummaryItem.SummaryType=DevExpress.Data.SummaryItemType.Count；
colTrademark.Visible=true；
宽度=113；
colModel.Caption=“Model”+i.ToString（）；
colModel.FieldName=“Model”+i.ToString（）；
colModel.Name=“colModel”+i.ToString（）；
colModel.Visible=true；
colModel.宽度=104；
gridBand[i].Caption=“Model”+i.ToString（）；
gridBand[i].Columns.Add（colTrademark）；
gridBand[i].Columns.Add（colModel）；
gridBand[i].Name=“gridBand”+i.ToString（）；
网格带[i].宽度=217；
}
advBandedGridView1.Bands.AddRange（gridBand）；
advBandedGridView1.GridControl=xgc；
advBandedGridView1.Name=“advBandedGridView1”；
xgc.MainView=advbandedgridview 1；
数据表dtCars=新数据表（“Cars”）；
dtCars.Columns.Add（“商标0”）；
dtCars.Columns.Add（“Model0”）；
dtCars.Columns.Add（“商标1”）；
dtCars.Columns.Add（“模型1”）；
DataRow drCars=dtCars.NewRow（）；
drCars[“商标0”]=“宝马”；
drCars[“Model0”]=“530i”；
drCars[“商标1”]=“aaaa”；
drCars[“Model1”]=“111”；
dtCars.Rows.Add（drCars）；
drCars=dtCars.NewRow（）；
drCars[“商标0”]=“凯迪拉克”；
drCars[“Model0”]=“塞维利亚”；
drCars[“商标1”]=“cccc”；
drCars[“Model1”]=“2222”；
dtCars.Rows.Add（drCars）；
drCars=dtCars.NewRow（）；
drCars[“商标0”]=“凯迪拉克”；
drCars[“Model0”]=“Deville”；
drCars[“商标1”]=“DDD”；
drCars[“Model1”]=“3333”；
dtCars.Rows.Add（drCars）；
xgc.DataSource=dtCars；

如何修复第二个问题？

我解决了这个问题。这可能会有帮助
