I have a situation where I need to generate the below XML dynamically in my C# code.
For example, the XML text would be 

<Envelope>
  <Body>
    <Login>
      <USERNAME>username</USERNAME>
      <PASSWORD>Sm@rt123</PASSWORD>
    </Login>
  </Body>
</Envelope>

The requirement is to send the above XML format as a string to an API call, which would get some responses as a string in the XML format.

My question is the above example is for a Login Api call, for all the api calls, the elements Envelope and Body are same and based on the api call, the other parts change like for Login api, I need to mention a xml element as Login with its attributes username and password.

Till now I have been hardcoding the above string and trying to test if the functionality is working fine, but now I need to automate this process of generating these tags for respective different api calls. I need to know how can this be done and what is the best approach for the same.

    I was going to suggest serialization as a simple way to output to XML. Here’s a simple example:

    First create the classes

    Public Class Login
    Public Property USERNAME() As String
        Get
            Return _USERNAME
        End Get
        Set(ByVal value As String)
            _USERNAME = value
        End Set
    End Property
    Private _USERNAME As String


    Public Property PASSWORD() As String
        Get
            Return _PASSWORD
        End Get
        Set(ByVal value As String)
            _PASSWORD = value
        End Set
    End Property
    Private _PASSWORD As String
End Class


Public Class Body
    Public Property Login() As Login
        Get
            Return _login
        End Get
        Set(ByVal value As LoginClass)
            _login = value
        End Set
    End Property
    Private _login As Login = New Login()
End Class


Public Class Envelope
    Public Property Body() As Body
        Get
            Return _body
        End Get
        Set(ByVal value As Body)
            _body = value
        End Set
    End Property
    Private _body As Body = New Body()
End Class

    Then, create an envelope object, populate it, and then serialize it:

    Dim envelope As New Envelope()
envelope.Body.Login.USERNAME = "username"
envelope.Body.Login.PASSWORD = "Sm@rt123"

Dim stream As MemoryStream = New MemoryStream()
Dim textWriter As XmlTextWriter = New XmlTextWriter(stream, New System.Text.UTF8Encoding(False))
Dim serializer As XmlSerializer = New XmlSerializer(GetType(Envelope))
Dim namespaces As XmlSerializerNamespaces = New XmlSerializerNamespaces()
namespaces.Add("", "")
serializer.Serialize(textWriter, envelope, namespaces)
Dim doc As XmlDocument = New XmlDocument()
doc.LoadXml(Encoding.UTF8.GetString(stream.ToArray()))
Dim xmlText As String = doc.SelectSingleNode("Envelope").OuterXml
