Hi,
Iam using vs2015. From C# I need to generate the XML file. Really I am very new to XML.
The tried the codes generates the XML file nicely.
C#
using namespace System::Xml;

    	XmlDocument^ Doc = gcnew XmlDocument();
		XmlDeclaration^ MyXmlDeclare = Doc->CreateXmlDeclaration("1.0", nullptr, nullptr);
		XmlElement^ MyRoot = Doc->DocumentElement;
		Doc->InsertBefore(MyXmlDeclare, MyRoot);

		XmlElement^ MyElement1 = Doc->CreateElement(String::Empty, "ENVELOPE", String::Empty);
		Doc->AppendChild(MyElement1);

		Doc->Save("C:\\Temp\\MyTallyPrgXML.xml");

But I get struck for the below XML lines. But I need it to generate it from C# 2015.
Kindly advice me to get succeed. Thanks
XML
<TALLYMESSAGE xmlns:UDF="TallyUDF">
  <VOUCHER VCHTYPE="Sales" ACTION="Create">
     <VOUCHERTYPENAME>Sales</VOUCHERTYPENAME>
     <ALLLEDGERENTRIES.LIST>
        <REMOVEZEROENTRIES>No</REMOVEZEROENTRIES>
        <ISDEEMEDPOSITIVE>Yes</ISDEEMEDPOSITIVE>
        <LEDGERFROMITEM>No</LEDGERFROMITEM>
        <LEDGERNAME>Customer 1</LEDGERNAME>
        <AMOUNT>-5000</AMOUNT>
     </ALLLEDGERENTRIES.LIST>
  </VOUCHER>
</TALLYMESSAGE>

That doesn't look like C#.

Definitely not - it's Managed C++.

First, create your classes:
C#
[XmlRoot(ElementName="ALLLEDGERENTRIES.LIST")]
public class ALLLEDGERENTRIESLIST { 

	[XmlElement(ElementName="REMOVEZEROENTRIES")] 
	public string REMOVEZEROENTRIES { get; set; } 

	[XmlElement(ElementName="ISDEEMEDPOSITIVE")] 
	public string ISDEEMEDPOSITIVE { get; set; } 

	[XmlElement(ElementName="LEDGERFROMITEM")] 
	public string LEDGERFROMITEM { get; set; } 

	[XmlElement(ElementName="LEDGERNAME")] 
	public string LEDGERNAME { get; set; } 

	[XmlElement(ElementName="AMOUNT")] 
	public int AMOUNT { get; set; } 
}

[XmlRoot(ElementName="VOUCHER")]
public class VOUCHER { 

	[XmlElement(ElementName="VOUCHERTYPENAME")] 
	public string VOUCHERTYPENAME { get; set; } 

	[XmlElement(ElementName="ALLLEDGERENTRIES.LIST")] 
	public ALLLEDGERENTRIESLIST ALLLEDGERENTRIESLIST { get; set; } 

	[XmlAttribute(AttributeName="VCHTYPE")] 
	public string VCHTYPE { get; set; } 

	[XmlAttribute(AttributeName="ACTION")] 
	public string ACTION { get; set; } 

	[XmlText] 
	public string Text { get; set; } 
}

[XmlRoot(ElementName="TALLYMESSAGE")]
public class TALLYMESSAGE { 

	[XmlElement(ElementName="VOUCHER")] 
	public VOUCHER VOUCHER { get; set; } 

	[XmlAttribute(AttributeName="UDF")] 
	public string UDF { get; set; } 

	[XmlText] 
	public string Text { get; set; } 
}
Then populate them with data.

Does that do the (unused) namespace?

It can do the hokey-cokey for all I care! :laugh:

Thank OtiginalGriff, Can you teach me to convert it in Managed C++/CLR
Thanks Again
This is easy to do with LINQ to XML[^]:
C#
XDocument document = new XDocument(
    new XDeclaration("1.0", null, null),
    new XElement("TALLYMESSAGE",
        new XAttribute(XNamespace.Xmlns + "UDF", "TallyUDF"),
        new XElement("VOUCHER",
            new XAttribute("VCHTYPE", "Sales"),
            new XAttribute("ACTION", "Create"),
            new XElement("VOUCHERTYPENAME", "Sales"),
            new XElement("ALLLEDGERENTRIES.LIST",
                new XElement("REMOVEZEROENTRIES", "No"),
                new XElement("ISDEEMEDPOSITIVE", "Yes"),
                new XElement("LEDGERFROMITEM", "No"),
                new XElement("LEDGERNAME", "Customer 1"),
                new XElement("AMOUNT", -5000)
            )
        )
    )
);

Thank Richard, can u explain me this line
XAttribute(XNamespace.Xmlns + "UDF", "TallyUDF")
Thanks

LINQ to XML uses XName instances to represent the name of elements and attributes.

If the name is in the default XML namespace, you can simply pass in a string, since there is an implicit conversion from string to XName.

If the name is in another namespace, you need to combine the local name with an instance of the XNamespace class.

In this case, your attribute is in the well-known xmlns namespace, so there is a static property on the XNamespace class to represent it.
