我有一个windows应用程序,在该应用程序中,我用两个数据表构建数据集,一个是"Products",另一个是是"TaxView"。我在下面包含了示例代码。在该代码中,我得到了错误Input array is longer than the number of columns in this table

 public DataTable[] getProductViewDetails(ArrayList ssd,ArrayList tax)
        {
            DataTable Products = new DataTable();
            DataColumn SalesDetailID = Products.Columns.Add("SalesDetailID", typeof(System.INT32));
            DataColumn BrandName = Products.Columns.Add("BrandName", typeof(System.String));
            DataColumn ProductName = Products.Columns.Add("ProductName", typeof(System.String));
            DataColumn Quantity = Products.Columns.Add("Quantity", typeof(System.INT32));
            DataColumn Rate = Products.Columns.Add("Rate", typeof(System.INT32));
            DataColumn Per = Products.Columns.Add("Per", typeof(System.String));
            DataColumn Discount = Products.Columns.Add("Discount", typeof(System.String));

            DataTable TaxView = new DataTable();
            DataColumn SalesTaxDetailID = Products.Columns.Add("SalesTaxDetailID", typeof(System.Int32));
            DataColumn TaxAmt = Products.Columns.Add("TaxAmt", typeof(System.Int32));
            DataColumn Total = Products.Columns.Add("Total", typeof(System.Int32));
            DataColumn TaxDesc = Products.Columns.Add("TaxDesc", typeof(System.String));
            DataColumn TaxValues = Products.Columns.Add("TaxValues", typeof(System.INT32));
            foreach (SalesStructDetails s in ssd)
            {
                //int previoustaxdetail;
                Products.Rows.Add(1,HP, Printer, 2, 2100, pcs, 125);
                foreach (TaxDetail t in tax)
                {                                       
                    if (s.SalesDetailId == t.SalesDetailID)
                    {
                        TaxView.Rows.Add(1, 125, 75, VAT, 4);
                    }
                }
            }
            DataTable[] dt = new DataTable[2] { Products, TaxView };
            return dt;
        }

我在TaxView.Rows.Add(1, 125, 75, VAT, 4);

";输入数组比该表中的列数“长”;在c#应用程序中

行出现错误

仔细查看-您正在将税列定义添加到products表中。将它们添加到税表中。示例:

DataTable TaxView = new DataTable();
DataColumn SalesTaxDetailID = Products.Columns.Add(blah);

应该是;

DataTable TaxView = new DataTable();
DataColumn SalesTaxDetailID = TaxView.Columns.Add(blah);

另外:考虑使用常规类而不是DataTable
