CSV解析出对象c#

Question

我需要一些帮助来解析 CSV 我们得到它是这样的

OrderNumber,LineNumber,CustomerNumber,CustomerName,AddressLine1,AddressLine2,AddressLine3,AddressLine4,AddressLine5,PostCode,ProductCode,ProductName,Ordered,Left,Picked

一个订单可以有多行，所以我们会得到

• 订单号
• 客户编号
• 客户姓名
• 地址线1
• 地址线2
• 地址线3
• AddressLine4
• 地址线5
• 邮政编码

多次匹配我需要一种方法来解析它成为这个结构

<orderDespatchRequest>
  <despatchDetails>
    <clientCustomerId>CustomerNumber</clientCustomerId>
    <clientOrderNumber>OrderNumber</clientOrderNumber>
    <dateDespatch>2015-07-01T00:00:00</dateDespatch>
    <despatchedDetail>
        <orderDespatchDetail>
            <lineNumber>LineNumber</lineNumber>
            <productCode>ProductCode</productCode>
            <productName>ProductName</productName>
            <quantity>Picked</quantity>
        </orderDespatchDetail>
    </despatchedDetail>
  </despatchDetails>
</orderDespatchRequest>

希望有人能提供帮助？

这就是我目前所得到的

        request.despatchDetails = despatchDetail;

        return SendOrderDespatch(request);

有了它可能会很顺利。 问候

作为示例，以下内容应该可以帮助您入门。

读取 CSV 文件

        var rows = (from row in File.ReadAllLines("Test.csv") 
                    let item = row.Split(',')
                    select new  
                    {
                        OrderNumber = item[0],
                        LineNumber = item[1],
                        CustomerID = item[2],
                        Company = item[3],
                        AddressLine1 = item[4],
                        AddressLine2 = item[5],
                        AddressLine3 = item[6],
                        AddressLine4 = item[7],
                        AddressLine5 = item[8],
                        PostCode = item[9],
                        ProductCode = item[10].ToString(),
                        ProductName = item[11].ToString(),
                        OrderQty = item[12],
                        OutstandingQty = item[13],
                        DespatchedQty = item[14]
         }).ToList();

将每个订单的数据分组为动态类型。

        var orders = from p in rows
                      group p by new { OrderNumber = p.OrderNumber, CustomerID = p.CustomerID } into g
                      select new { OrderNumber = g.Key.OrderNumber, CustomerID = g.Key.CustomerID, OrderLines = g.ToList() };

创建 XML 文件（请注意输出的 xml 将不符合您的确切要求，但此示例应该可以帮助您进行操作）。

        var xEle = new XElement("Orders",
                      from order in orders
                      select new XElement("Order",
                                   new XAttribute("OrderNumber", order.OrderNumber),
                                     new XElement("CustomerId", order.CustomerID)
                                 , from line in order.OrderLines 
                                       select new XElement("Line",   new XAttribute("ProductCode", line.ProductCode),
                                     new XElement("OrderQty", line.OrderQty))));



        xEle.Save("orders.xml");
        Console.WriteLine("Converted to XML");
