问题描述
如何将以下嵌套的 XML 加载到数据集中?
How do I load the following nested XML into a DataSet?
<items>
<item>
<id>i1</id>
<name>item1</name>
<subitems>
<name>subitem1</name>
<name>subitem2</name>
</subitems>
</item>
<item>
<id>i2</id>
<name>item2</name>
<subitems>
<name>subitem1</name>
<name>subitem2</name>
</subitems>
</item>
</items>
我可以得到尽可能多的项目"表,但我如何获得子项目?
I can get as far as a the "item" table but how do I get the subitems?
MemoryStream itemsStream = new MemoryStream(Encoding.ASCII.GetBytes(itemsXML));
DataSet itemsSet = new DataSet();
itemsSet.ReadXml(itemsStream);
foreach (DataRow itemRow in itemsSet.Tables["item"].Rows) {
Console.WriteLine("column id=" + itemRow["id"] as string + " name=" + itemRow["name"] as string);
}
推荐答案
这对我有用,我唯一的自由是更改子项的字段名称.
This works for me, the only liberty I have taken is to Change the field name for the subitems.
子项的原始 XML
<subitems>
<name>subitem1</name>
<name>subitem2</name>
</subitems>
为子项修改 XML
<subitems>
<name1>subitem1</name1>
<name2>subitem2</name2>
</subitems>
这里是代码.
DataSet myDS = new DataSet();
DataTable myTable = new DataTable("item");
myTable.Columns.Add("id", typeof(string));
myTable.Columns.Add("name", typeof(string));
myTable.Columns.Add("name1", typeof(string));
myTable.Columns.Add("name2", typeof(string));
myDS.Tables.Add(myTable);
string xmlData = "<items> <item> <id>i1</id> <name>item1</name> <subitems> <name1>subitem1</name1> <name2>subitem2</name2> </subitems> </item> <item> <id>i2</id> <name>item2</name> <subitems> <name1>subitem3</name1> <name2>subitem4</name2> </subitems></item></items>";
System.IO.MemoryStream itemsStream = new System.IO.MemoryStream(Encoding.ASCII.GetBytes(xmlData));
myDS.ReadXml(itemsStream, XmlReadMode.IgnoreSchema);
foreach (DataRow itemRow in myDS.Tables["item"].Rows)
{
MessageBox.Show("column id=" + itemRow["id"] + " name=" + itemRow["name"]);
MessageBox.Show(itemRow["name1"].ToString() + " - " + itemRow["name2"].ToString());
}
