Question

我需要阅读一个XML文件，其中包含常规订购数据以及有关订购产品的详细信息。我将常规订单数据放置在dataGridView中。在第二个DGV中，他想输入选定顺序的数据，例如<positionitem>, <materialcode>, <materialcatalognumber>, <materialdescription>, <quantity>, <unit>代表标签<DocId> = 222。

我在Visual Studio Community 2017中创建代码

下面的代码从变量“ pobraneDane”和XML数据中读取订单数据。

XmlDocument doc = new XmlDocument();
doc.LoadXml(pobraneDane);
XmlNodeList DocId = doc.GetElementsByTagName("DocId");
XmlNodeList DocNoExternal = doc.GetElementsByTagName("DocNoExternal");
XmlNodeList DocNo = doc.GetElementsByTagName("DocNo");            
for (int i = 0; i < doc.Count; i++)
{
    dataGridView1.Rows.Add(DocId[i].InnerXml, DocNoExternal[i].InnerXml, DocNo[i].InnerXml);
}

我想问一个示例代码，该代码将提取所选订单的详细信息-订单号为：<DocId> 订单详细信息例如<MaterialCode>

预先感谢您的帮助。
