DataTable 基本转换简单实例

var query = from dt in tblProduct.AsEnumerable()
where dt.Field<string>("StockNo") ==""
select dt;
if (query.ToList().Count > 0)
{
Alert.ShowInTop("数据不全,仓库不能为空");
return;
}

var queryDesc = from dt in tblProduct.AsEnumerable()
orderby dt.Field<string>("Count") descending
select dt;
tblProduct = queryDesc.CopyToDataTable();

foreach (DataRow Row in tblProduct.Rows)
{ if (Row["ProductNo"].ToString() == itemNO)
{ Row["Count"] ="";}
}
