我有一个ASP.NET DataTable，我从另一组ASP填充：TextBox字段存储到然后批量插入数据库当我点击添加按钮我得到System.Web.UI.WebControls.TextBox添加到DataTable而不是我在字段中输入的数据，任何人都可以告诉我这里我做错了什么。

你忘记了.Text财产;用它来指定你的控件文本：
row["AccountRef"] = txtAccountRef.Text;
row["InvRef"] = txtInvoiceRef.Text;
row["CustOrderNo"] = txtCustOrderNo.Text;
row["Product"] = txtProduct.Text;
row["Qty"] = txtQty.Text;
row["UnitAmount"] = txtUnitAmount.Text;
row["Value"] = txtValue.Text;
row["TakenBy"] = txtTakenBy.Text;

您的问题是AddDataToTable()方法。您可以像这样定义该函数的参数：
string AccountRef
但是然后将值分配给这样的行：
row [“AccountRef”] = txtAccountRef;
看到区别？第二个摘录是在您的页面上使用控件，而不是您传入的参数。您应该将其更改为如下所示：
row [“AccountRef”] = AccountRef;
