[求助]关于C#中Dataset操作XML的问题

[snowhero]

求教高手如何使用C#中的DataSet生成如下内容的XML文件，要求格式完全相同且要使用DataSet手动生成，主要是不知如何将dt2节点作为dt1节点的子节点：
test.xml:
<?xml version="1.0"?>
<testds>
<dt1 name="dt1">
<id>a</id>
<dt1c2>111</dt1c2>
<dt2 name="dt2">
<dt2c1>d2</dt2c1>
<dt2c2>adad</dt2c2>
</dt2>
</dt1>

</testds>

将 dt1 和 dt2 建立 Relations, 并将其内嵌显示设置为 True

Dim objConn As OracleConnection
Dim objDataAdapter As OracleDataAdapter
Dim strConn As String = "user id=scott;password=tiger;data source=orcl"
Dim strSql As String
Dim ds As DataSet
Dim objXmlDataDoc As XmlDataDocument
Try
objConn = New OracleConnection(strConn)
ds = New DataSet("DeptEmp")

strSql = "select * from emp"
objDataAdapter = New OracleDataAdapter(strSql, objConn)
objDataAdapter.Fill(ds, "Employee")

strSql = "select * from dept"
objDataAdapter.SelectCommand.CommandText = strSql
objDataAdapter.Fill(ds, "Dept")

ds.CaseSensitive = False
ds.Relations.Add("DeptEmployees", _
ds.Tables("Dept").Columns("DeptNo"), _
ds.Tables("Employee").Columns("DeptNo")).Nested = True

ds.WriteXml("DeptEmployees.xml")

Catch ex As Exception
Console.WriteLine(ex.Message)
Console.ReadLine()
End Try
