Access web service WSDL file in dynamically in client side using C#

Introduction

Web Service

{codecitation class="brush: csharp; gutter: true;" width="650px"}


using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;

namespace SampleWebservice
{
///
/// Summary description for FileCreateServices
///
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
// [System.Web.Script.Services.ScriptService]
public class FileCreateServices : System.Web.Services.WebService
{

[WebMethod]
public bool CreateFile(string[] collectionUsers)
{
bool result = false;
ServerFileManager manager = new ServerFileManager();
manager.CollectionofUsers = collectionUsers;
manager.CreateFile();
return result = true;
}
}
}

ServerFileManager.cs

{codecitation class="brush: csharp; gutter: true;" width="650px"}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.IO;

namespace SampleWebservice
{
public class ServerFileManager
{

public ServerFileManager()
{

}

string[] collectionofUsers = null;

public string[] CollectionofUsers
{
get { return collectionofUsers; }
set { collectionofUsers = value; }
}
public void CreateFile()
{
if (collectionofUsers != null)
{
using (FileStream stream=new FileStream(@"c:\UserDetails.txt",FileMode.Append))
{
using (StreamWriter writer=new StreamWriter(stream))
{
foreach (string username in collectionofUsers)
{
writer.WriteLine(username);
writer.Flush();
}
}
}
}
}
}
}

Both class are simple and basic code lines.Again say we are going to create user name list file in the server , which file supply from

client application.But our demonstration is use the WSDL file and access web service method in client Application.

Let's compile web service project and run ,when you will see its look like this way in IE.

But we need WSDL file to access in out side. how you can generate WSDL file from the .asmx file it's pretty easy just type like this

on your IE http://localhost:14057/FileCreateServices.asmx?WSDL then you will see like this xml file structure on your IE.

Fine we have WSDL file structure ,just save in your local directory with extension .wsdl using IE save as Menu.

Lets start i important step here,We need generate proxy class to access Web service method from using WSDl file, then only you access the web service method in your client application.

Note:if you are add web reference using Visual studio , we don't do those steps because of Visual studio generate proxy class for us.

To generate proxy class we need access WSDL.exe application which come with .NET 2.0. just look following figure to learn how to generate proxy class using wsdl.exe with command prompt.

Let's open command prompt and type following commands in command prompt.

Setting environment for using Microsoft Visual Studio 2008 x86 tools.

{codecitation class="brush: plain; gutter: true;" width="650px"}

Note: I have installed Visual studio on D Drive.To learn passing parameter to WSDL.exe just visit here

Now we have cs file i n our bin directory just copy and paste in your client project. when your add with your client appliction it like be followings.

This is your client application

lets write client code in within the client application this code look like followings

{codecitation class="brush: csharp; gutter: true;" width="650px"}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using CodeGainService;
namespace WDSLDemo
{
    class Program
    {
        static void Main(string[] args)
        {
            FileCreateServices services = new FileCreateServices();
            services.Url = "http://localhost:14057/FileCreateServices.asmx";
            string [] collection=new string[]{"Testor1",
            "Testor2",
            "Testor3",
                "Testor4",
                    "Testor5",
                        "Testor5",
            "Testor6"
            };
            bool result =services.CreateFile(collection);
            if (result)
            {
                Console.WriteLine("Done");
            }
            else
            {
                Console.WriteLine("failed");
            }
            Console.ReadLine();
        }
    }
}
{/codecitation}

Output: File create in server side and "Done " message come in the Console.

Conclusion

I hope this article will helpful to most of the developers who are need access web service methods using WSDL file without adding Web References .Please make comment about the article.

Sample code
