Calling Web Service Using SOAP Request In Console Application

public void InvokeService(int a, int b) {  
  //Calling CreateSOAPWebRequest method    
  HttpWebRequest request = CreateSOAPWebRequest();  
  
  XmlDocument SOAPReqBody = new XmlDocument();  
  //SOAP Body Request    
  SOAPReqBody.LoadXml(@ "<?xml version="  
   "1.0"  
   " encoding="  
   "utf-8"  
   "?>   < soap: Envelope xmlns: soap = ""  
   http: //schemas.xmlsoap.org/soap/envelope/"" xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema"">    
   < soap: Body >  
   < Addition xmlns = ""  
   http: //tempuri.org/"">    
   < a > " + a + @" < /a>   < b > " + b + @" < /b>   < /Addition>   < /soap:Body>   < /soap:Envelope>");    
  
  
   using(Stream stream = request.GetRequestStream()) {  
    SOAPReqBody.Save(stream);  
   }  
   //Geting response from request    
   using(WebResponse Serviceres = request.GetResponse()) {  
       using(StreamReader rd = new StreamReader(Serviceres.GetResponseStream())) {  
           //reading stream    
           var ServiceResult = rd.ReadToEnd();  
           //writting stream result on console    
           Console.WriteLine(ServiceResult);  
           Console.ReadLine();  
       }  
   }  
} 

Now call the above method from main method by writing the following code as:

static void Main(string[] args)    
{    
    //creating object of program class to access methods    
    Program obj = new Program();    
    Console.WriteLine("Please Enter Input values..");    
    //Reading input values from console    
    int a = Convert.ToInt32(Console.ReadLine());    
    int b = Convert.ToInt32(Console.ReadLine());    
    //Calling InvokeService method    
    obj.InvokeService(a, b);    
}

Now whole code in Program.cs file will look like the following:

using System;  
using System.IO;  
using System.Net;  
using System.Xml;  
  
namespace UsingSOAPRequest  
{  
    public class Program  
    {  
        static void Main(string[] args)  
        {  
            //creating object of program class to access methods  
            Program obj = new Program();  
            Console.WriteLine("Please Enter Input values..");  
            //Reading input values from console  
            int a = Convert.ToInt32(Console.ReadLine());  
            int b = Convert.ToInt32(Console.ReadLine());  
            //Calling InvokeService method  
            obj.InvokeService(a, b);  
        }  
        public void InvokeService(int a, int b)  
        {  
            //Calling CreateSOAPWebRequest method  
            HttpWebRequest request = CreateSOAPWebRequest();  
  
            XmlDocument SOAPReqBody = new XmlDocument();  
            //SOAP Body Request  
            SOAPReqBody.LoadXml(@"<?xml version=""1.0"" encoding=""utf-8""?>  
            <soap:Envelope xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/"" xmlns:xsi=""http://www.w3.org/2001/XMLSchema-   instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema"">  
             <soap:Body>  
                <Addition xmlns=""http://tempuri.org/"">  
                  <a>" + a + @"</a>  
                  <b>" + b + @"</b>  
                </Addition>  
              </soap:Body>  
            </soap:Envelope>");  
  
  
            using (Stream stream = request.GetRequestStream())  
            {  
                SOAPReqBody.Save(stream);  
            }  
            //Geting response from request  
            using (WebResponse Serviceres = request.GetResponse())  
            {  
                using (StreamReader rd = new StreamReader(Serviceres.GetResponseStream()))  
                {  
                    //reading stream  
                    var ServiceResult = rd.ReadToEnd();  
                    //writting stream result on console  
                    Console.WriteLine(ServiceResult);  
                    Console.ReadLine();  
                }  
            }  
        }  
  
        public HttpWebRequest CreateSOAPWebRequest()  
        {  
            //Making Web Request  
            HttpWebRequest Req = (HttpWebRequest)WebRequest.Create(@"http://localhost/Employee.asmx");  
            //SOAPAction  
            Req.Headers.Add(@"SOAPAction:http://tempuri.org/Addition");  
            //Content_type  
            Req.ContentType = "text/xml;charset=\"utf-8\"";  
            Req.Accept = "text/xml";  
            //HTTP method  
            Req.Method = "POST";  
            //return HttpWebRequest  
            return Req;  
        }  
    }  
}

Now run the console application, then the console window will look like as follows and enter the input values as:

Now press enter button, it will give the response in XML format as follows:

In preceding console window you have seen web service response in the form of XML format which contains the output as 300. I hope from all above examples you have learned how to call web service using SOAP request in console application.

Notes

• Download the Zip file of the sample application for a better understanding.
• Apply proper validation as per your need.
