dotnet xml: Disappointed, this is not the first time I'm posting this kind of a request
for help, but no helpful answer was posted yet.

I'll try make my question as clear as I can:

(1) I wish to write an XML file. this file will contain any number of
parameters to be used in my C# code as database.
(2) This file may contain any number of parameters, and I will know the
number of the parameters only at run time.
(3) Any parameter must have a name, but this name may be any name, and I
will know the names of the parameters only at run time.
(4) Any parameter must have a type, this type can be of any well known type
(int, string, float, dateTime, byte etc.), and I will know these types only
at run time.
(5) Any parameter may or may not have several more attributes
(authorization, precision, range), I will now if any of this attributes exist
only at run time.
(6) Any parameter will have a value of the type as described above.

I need to read this parameters form the XML file as their real value without
doing any code switching, and to assign these values to my run time data
members.

I thought I'll be able to load the XML file into DataSet and read the
parameters from it. But I'll be happy to use any other solution you may have.

Thanks

Ok, I think I found a way to do thanks to Marc Clifton articale on
CodeProject (http://www.codeproject.com/dotnet/MycroXaml.asp).

The XML file can be somthing like that:

<?xml version="1.0" encoding="utf-8"?>
<System Name="System">
<Paramaters>
<Speed type="System.Iint32">111</Speed >
<_xAxis type="System.Single">222</_xAxis>
<_yAxis type="System.Double">333</_yAxis>
<_ID type="System.Int64">444</_ID>
<_Name type="System.String">String value...</_Name>
</Paramaters>
</System>


And the C# code can be:

System.IO.StreamReader sr = new System.IO.StreamReader("TypesDef.xml");
string text = sr.ReadToEnd();
sr.Close();
XmlDocument doc = new XmlDocument();
doc.LoadXml(text);
XmlNode node = doc.FirstChild;
while( node.NodeType.ToString() != "Element" )
{
node = node.NextSibling;
}

XmlNode paramsNode = doc.SelectSingleNode("//Paramaters");
XmlNodeList nodeList = paramsNode.ChildNodes;
Hashtable verTypes = new Hashtable(nodeList.Count);
string typeName = "";
Type type;

foreach( XmlNode xmlNode in nodeList )
{
XmlAttribute attr = xmlNode.Attributes["type"];
typeName = attr.Value;
if( typeName == "System.String" )
{
verTypes[xmlNode.Name] = xmlNode.InnerText;
}
else
{
type = Type.GetType(typeName, false);
object typeIntance = Activator.CreateInstance(type);
System.Reflection.MethodInfo Parse = type.GetMethod("Parse", new Type
[] {typeof(String)});
verTypes[xmlNode.Name] = Parse.Invoke(type, new object[]
{xmlNode.InnerText});
}
}
