In my previous article we discussed SOAP Message Versions. Now let us move ahead and create a message.

You can create a Message using the CreateMessage() method of the Message class. This method is overloaded with 11 different sets of input parameters.

The easiest way to create a message is by just providing the MessageVersion and an action:

When the above code snippet is run you will get a message as output and if you notice there is no body in the message since we have not added that.

If you want to add a body to the message you can do that but the restriction is that you can only add a serialized object as a message body.
Let us add a string to the message body. Since strings and other built-in types are by default serializable. So we do not need to explicitly serialize it.

In the above function we have added a string message body with the value "HI I am Body". When running the above code snippet you will get output as below:

Let us create a message as an object of a custom class as the message body. Assume you have a custom class called Product.

And you want to create a message having an instance of this class as the message body. You can very much do that as below:

On running the above code you will get output as below:

And you can see the custom object is part of the message.
For your reference the code for you to copy is given below:
Program.cs

using System;
using System.ServiceModel.Channels;
using System.ServiceModel;
using System.Xml;
using System.Collections.Generic;
namespace XML
{
    class Program
    {     

        static void Main(string[] args)
        {

            Message msg = Message.CreateMessage(MessageVersion.Soap11,
"urn:MyAction");
            Console.WriteLine(msg.ToString());
            Console.ReadKey(true);
 
            msg = Message.CreateMessage(MessageVersion.Soap11WSAddressing10,
                                         "urn:MyAction",
                                         "Hi I am Body");

            Console.WriteLine(msg.ToString());
            Console.ReadKey(true);
 
            Product p = new Product
            {
                ProductId = 1,
                ProductName = "Books",
                ProductPrice = 110.0
            };
            msg = Message.CreateMessage(MessageVersion.Soap12,
                                        "urn: MY Action",
                                        p);
            Console.WriteLine(msg.ToString());
            Console.ReadKey(true);           
 
          
 
        }
 

    }

    public class Product
    {
        public int ProductId { get; set; }
        public string ProductName { get; set; }
        public double ProductPrice { get; set; }
    }
}


Now you know how you can create a message in WCF. I hope this article was useful. Thanks for reading.
