Consume Salesforce Web service in C# .Net Application

In this example, we are going to consume the enterprise WSDL of the Salesforce in C# application.

Log into the Salesforce and navigate to “Your Name | Setup | App Setup | Develop | API” and select the “Generate Enterprise WSDL”.  Copy the URL, as we will need this in our C# Application.

Now Open Visual Studio (I am using Visual Studio 2010) and create new Windows Application. The UI of the application should look like:

C# Application to consume salesforce webservice

Right click on the “References“ folder and select “Add Service Reference“.

Now select the “Advanced“ and then select “Add Web Reference…“
Provide the URL of the generated WSDL, which we have discussed above in this tutorial.
It will prompt you for the username and password of salesforce, so provide it. After validation, it will display you below screen. Provide ” the web reference name” which will be used in program. In this case, the web reference name is “SFDC_Enterprise_WSDL“.

Add the following code in c# application:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Web.Services.Protocols;
using SFDCWebServiceExample.SFDCCustom;
using SFDCWebServiceExample.SFDC_Enterprise_WSDL;

namespace SFDCWebServiceExample
    public partial class Form1 : Form
        private SforceService binding;
        private LoginResult lr;
        private SaveExpenditureWebServiceService myBinding = new SaveExpenditureWebServiceService();

        public Form1()

        private void btnLogin_Click(object sender, EventArgs e)

            if (login())

        private bool login()
                binding = new SforceService();
                binding.Timeout = 6000;
                lr = binding.login(txtUserName.Text, txtPwd.Text);
                return true;
            catch (SoapException e)
            return false;
        private void describeGlobal()
            binding.Url = lr.serverUrl;
            #region[Consume Enterprise webservice]

            binding.SessionHeaderValue = new SFDC_Enterprise_WSDL.SessionHeader();
            binding.SessionHeaderValue.sessionId = lr.sessionId;

            //describeGlobal returns an array of object results that
            //includes the object names that are available to the logged-in user

            DescribeGlobalResult dgr = binding.describeGlobal();

            //Loop through the array echoing the object names to the console
            StringBuilder sb = new StringBuilder();
            for (int i = 0; i < dgr.sobjects.Length; i++)
                sb.Append(dgr.sobjects[i].name+" , ");

Note :
After Successful login, set the “SessionHeaderValue” and “SessionHeaderValue.sessionId”, In this program, we are displaying the comma separated name of all the available objects available to logged in user.

    Hi Jitendra
    When I pass username and password or any organization.
    it connect but i can’t access wsdl of that organization to access its custom objects because every organization have its custom objects.
    Basically i want to add web reference of wsdl on run time.

      Hi Shailendra,
      I have not tried this and i think it would not be straight forward.
      You can easily bind webservices – WSDL dynamically in c#, However to get the web reference of salesforce enterprise wsdl, we have to supply the credentials of the organizations.
      I will try to find out the solution, in mean while if you get the answer please post here so that others can get benefited.

      Hi Shailendra,
      Instead of Enterprise WSDL, use the Partner WSDL.
      It would work in this scenario.

    Hi All,

    I have to use BULK API functionality of Salesforce in C#. Just want to know first which WSDL should I use Enterprise one or the Partner one? I have downloaded Partner Web Services API Version 24.0 but it seems it doesn’t have those required parameters what I am looking for.

    Please guide.

      Partner WSDL is very generic, give a try to Enterprise WSDL however it is tightly coupled and have its own disadvantages.

    This is talking about inserting data into salesforce. Do you have an example to push data from salesforce (to Biztalk)? I need to push data out for each Case insert/update.

    Hi Jitendra,

    I am trying to setup Delegated Authentication for communitiies. I have followed all the steps provided on Salesforce help but I am unable to figure out which Salesforce URL to use to perform Post operation to SFDC so that my Webservice will get called.

    I have tested the Webservice that is working fine but I am not sure which URL to perform Post operation and how in which format?

    Any help, will be highly appreciated.
