How to insert XML document to xml

I have a XML document that I have to insert into data set..
Here's the part of the code:
string XmlFilePath = "C:\\Inetpub\\wwwroot\\Test_AGR_2.xml";
XmlDocument XmlDoc = new XmlDocument();
XmlDoc.Load(XmlFilePath);
So this XmlDoc I have to insert into a data-set but without any conversion to string or what so ever!.
Thanks in advance!

You can load XML directly to DataTable with DataTable.ReadXml function, then add DataTable to your DataSet.
https://msdn.microsoft.com/en-us/library/fs0z9zxd(v=vs.110).aspx

You can use DataTable.ReadXml function, BUT, the xml schema must be coherent to the dataset class.
The xml should look like this:
<?xml version="1.0" standalone="yes"?>
<testDS>
<testDT>
<testCol>0</testCol>
</testDT>
<testDT>
<testCol>1</testCol>
</testDT>
<testDT>
<testCol>2</testCol>
</testDT>
</testDS>
Instead you have to manually parse xml using XmlDocument and create the dataset with the data that you read.

Reading Custom XML File

This is Guardian.re, which is a custom XML file that I've createed in C#. I have created a new program that I want to read this file and place the info in a listbox. The xmlns being the name of the user that was entered. How do I do this?
<?xml version="1.0" encoding="utf-8"?>
<!--This is the Guardian Submit file. An admin will read with their viewers.-->
<Guardian
Age="5"
Hours="5"
Why="Why?"
Qualify="What qualifies you?"
xmlns="Name" />
Here is the C# source:
if (System.IO.File.Exists("Guardian.re") == false)
{
//.re is the file extension that is used
XmlWriter writer = XmlWriter.Create(#"Guardian.re");
writer.WriteStartDocument();
writer.WriteComment("This is the Guardian Submit file. An admin will read with their viewers.");
//Element <Guardian> in the .re XML format
writer.WriteStartElement("Guardian", IGN);
//the element <Age> in the .re XML format
writer.WriteAttributeString("Age", Age);
//the element <Hours> in the .re XML format
writer.WriteAttributeString("Hours", hours);
//the element <Why> in the .re XML format
writer.WriteAttributeString("Why", WhyRank);
//the element <Qualify> in the .re XML format
writer.WriteAttributeString("Qualify", Qualify);
writer.WriteEndElement();
writer.Flush();
writer.Close();
}

Use XPath to get your individual values back from the file as found here
http://support.microsoft.com/kb/308333
and then add the values to the listbox as specified here
http://msdn.microsoft.com/en-us/library/aa288403(v=vs.71).aspx
You can also find some code here Parse XML and populate in List Box

I posted a possible answer for this here: Reading an XML File With Linq
Guess I probably should have waited, as the other is in regards to Linq...

Display deserialized XML on ASP.NET page

How can I display XML output on ASP.NET page with XML tags?
XmlDocument doc = (XmlDocument)JsonConvert.DeserializeXmlNode(jsonOutput, "root");
Console.WriteLine(doc.OuterXml);
I would like to get results on my page like this:
<root>
<id>108013515952807</id>
<posts>
<data>
<message>This...Game... http://www.youtube.com/watch?v=l8Xsex0pqXY</message>
<id>108013515952807_470604423027046</id>
<created_time>2013-05-15T20:02:31+0000</created_time>
</data>
<data>
<message>Streaming in a few minutes! http://www.youtube.com/watch?v=IYnHDT6V82k</message>

<created_time>2013-05-15T16:46:36+0000</created_time>
</data>
</posts>
</root>
I tried this but I get no XML tags like in example above.
Response.Write("<BR>" + doc.OuterXml);

If you just put XML onto a webpage, the browser thinks it might be HTML and "renders" it, which is why you can't see the tags. You need to encode the XML
You can use the method
Response.Write(Server.HtmlEncode(doc.OuterXml));

Try
XElement.Parse(request.OuterXml).ToString()
If you want prettified XML string,
refer to: What is the simplest way to get indented XML with line breaks from XmlDocument?

load xml file into memory

I need to load a xml file in memory so I can access it several times from different forms.
The xml is in this format:
<Slides>
<Slide>
<Name>Name 1</Name>
<Value>Value 1</Value>
<Type>Type 1</Type>
</Slide>
<Slide>
<Name>Name 2</Name>
<Value>Value 2</Value>
<Type>Type 2</Type>
</Slide>
</Slides>
I don't want to use a database to store the vars. Is there any other method to store the data in memory?
Right now I'm using a txt file for each slide and streamreader, which I'm sure is not the best option.
EDIT:
I added this code, but will I be able to get the slides every time without reading the xml file again?
var slides = from s in XElement.Load("slides.xml").Elements("Slide")
select s;
foreach (var slide in slides)
{
//code
}

You should use the XDocument Load method: http://msdn.microsoft.com/en-us/library/bb343181.aspx
i think it is better to use XDocument than the XmlDocument... but it depends on your requirements...
The XDocument is more memory optimized than the XmlDocument, and i think they both are easy for use (for getting values from the xml)

See the XmlDocument class. The Load() method does what you want.

First you have to save the xml file in your project file or your hard disk.Then only you can load the xml file in code behind.
You can create xml file dynamically.it will be much better.
using System.Xml;
XmlDocument myxml = new XmlDocument();
myxml.Load("D:/sample.xml");//Load you xml file from you disk what you want to load
string element_1 = myxml.GetElementsByTagName("Name")[0].InnerText;
string element_2 = myxml.GetElementsByTagName("Value")[0].InnerText;
string element_3 = myxml.GetElementsByTagName("Value")[0].InnerText;
string element_4 = myxml.GetElementsByTagName("Name")[1].InnerText;
string element_5 = myxml.GetElementsByTagName("Value")[1].InnerText;
string element_6 = myxml.GetElementsByTagName("Value")[1].InnerText;
Try this program it will help you.

Reading contents of XML file without having to remove the XML declaration

I want to read all XML contents from a file. The code below only works when the XML declaration (<?xml version="1.0" encoding="UTF-8"?>) is removed. What is the best way to read the file without removing the XML declaration?
XmlTextReader reader = new XmlTextReader(#"c:\my path\a.xml");
reader.Read();
string rs = reader.ReadOuterXml();
Without removing the XML declaration, reader.ReadOuterXml() returns an empty string.
<?xml version="1.0" encoding="UTF-8"?>
<s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope" xmlns:a="http://www.w3.org/2005/08/addressing">

Update
I know other methods that use NON-xml reader (e.g. by using File.ReadAllText()). But I need to know a way that uses an xml method.

There can be no text or whitespace before the <?xml ?> encoding declaration other than a BOM, and no text between the declaration and the root element other than line break.
Anything else is an invalid document.
UPDATE:
I think your expectation of XmlTextReader.read() is incorrect.
Each call to XmlTextReader.Read() steps through the next "token" in the XML document, one token at a time. "Token" means XML elements, whitespace, text, and XML encoding declaration.
Your call to reader.ReadOuterXML() is returning an empty string because the first token in your XML file is an XML declaration, and an XML declaration does not have an OuterXML.
Consider this code:
XmlTextReader reader = new XmlTextReader("test.xml");
reader.Read();
Console.WriteLine(reader.NodeType); // XMLDeclaration
reader.Read();
Console.WriteLine(reader.NodeType); // Whitespace
reader.Read();
Console.WriteLine(reader.NodeType); // Element
string rs = reader.ReadOuterXml();
The code above produces this output:
XmlDeclaration
Whitespace
Element
The first "token" is the XML declaration.
The second "token" encountered is the line break after the XML declaration.
The third "token" encountered is the <s:Envelope> element. From here a call to reader.ReadOuterXML() will return what I think you're expecting to see - the text of <s:Envelope> element, which is the entire soap packet.
If what you really want is to load the XML file into memory as objects, just call
var doc = XDocument.Load("test.xml")
and be done with the parsing in one fell swoop.
Unless you're working with an XML doc that is so monstrously huge that it won't fit in system memory, there's really not a lot of reason to go poking through the XML document one token at a time.

What about
XmlDocument doc=new XmlDocument;
doc.Load(#"c:\my path\a.xml");
//Now we have the XML document - convert it to a String
//There are many ways to do this, one should be:
StringWriter sw=new StringWriter();
doc.Save(sw);
String finalresult=sw.ToString();

EDIT: I'm assuming you mean you actually have text between the document declaration and the root element. If that's not the case, please clarify.
Without removing the extra text, it's simply an invalid XML file. I wouldn't expect it to work. You don't have an XML file - you have something a bit like an XML file, but with extraneous stuff before the root element.

IMHO you can't read this file. It's because there's a plain text before the root element <s:Envelope> which makes whole document invalid.

You're parsing an XML document as XML just to obtain the source text? Why?
If you really want to do that then:
string rs;
using(var rdr = new StreamReader(#"c:\my path\a.xml"))
rs = rdr.ReadToEnd();
Will work, but I'm really not sure that is what you actually want. This pretty much ignores that it's XML and just reads the text. Useful for some things, but not a lot.
