I am using the code below (simplified for this example) to post data to a SharePoint list
StringBuilder customerDoc = new StringBuilder();
customerDoc.Append("<Method ID='1' Cmd='New'>");
customerDoc.Append("<Field Name='Name'>" + Name + "</Field>");
customerDoc.Append("<Field Name='Age'>" + age + "</Field>");
customerDoc.Append("<Field Name='City'>" + city + "</Field>");
customerDoc.Append("<Field Name='Country'>" + country + "</Field>");
customerDoc.Append("</Method>");
XmlDocument xDoc = new XmlDocument();
XmlElement xBatch = xDoc.CreateElement("Batch");
xBatch.SetAttribute("OnError", "Continue");
xBatch.InnerXml = sb_method.ToString();
XmlNode xn_return = sharePoint.listsObj.UpdateListItems(ConfigurationManager.AppSettings["SaveCustomer"].ToString(), xBatch);

Let's say I wanted to create a user control from a raw string rather than a .ascx file, how would I do that? Temp files are not an option. Is this even possible? I can't find anything online about this.

How would I create a type while knowing just the name of the type in string form example...
My aspx contains this and some bindable control
<asp:EntityDataSource ID="EntityDataSource1" runat="server"
ConnectionString="name=MyEntities" DefaultContainerName="MyEntities"
EntitySetName="MyData">
</asp:EntityDataSource>
Now from code I need to be able to create an instance of EntitySetName="MyData". Keep in mind I will not know these names until runtime tho. I can do EntityDataSource1.EntitySetName and this gives me the name in string form. But now I need to create and instance of it and get access to the members so I can manipulate the data. I have been trying Activator.CreateInstance and used various overloaded versions of it. Bottom line tho is I am not seeing how to do this. I keep running into trying to cast something into a type when all I have is the name of the type.

I have a few classes: SomeClass1, SomeClass2.
How can I create a new instance of one of these classes by using the class name from a string?
Normally, I would do:

var className = "SomeClass1";
I am assuming I should use Type.GetType() or something
I am sending a request to a web service which requires a string containing XML, of which I have been giving an XSD.
I've ran xsd.exe and created a class based on this but am unsure of the best way to create the xml string to send, for example a stream, XMLDocument or some form of serialization.
UPDATE
I found this here
public static string XmlSerialize(object o)
{
using (var stringWriter = new StringWriter())
{
var settings = new XmlWriterSettings
