XML元素不显示空值 [英] XML element not displaying for null values

问题描述

我使用以下代码将xml文件导入数据库。

Hi,

I am using an xml file to import into the database using the below code.

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(path + "Data.xml");
XmlNodeList nodeList = xmlDoc.DocumentElement.SelectNodes("/DocumentElement/Profile");
//read XML data and ID is one of the column
object[] ID = XDocument.Load(path + "Data.xml").Descendants("ID").Select(element => Element.Value).ToArray();

现在ID元素具有空值，当我读取它们时，省略了具有空值的行。如何为这些空节点设置空字符串值？

Now the ID element has null values and when I read them the rows with null values are omitted. How can I set empty string values for those null nodes?
