In this blog post, you will learn how to consume the WCF REST service in the C# ASP.Net web application. Previously I have explained how to create WCF REST Service in C# and Exception Handling in WCF using Fault Contract. You can follow the below steps to calling WCF rest service:-
- First of all, you need to host WCF restful service somewhere on the webserver or at IIS on the local machine. In my example the URL of that XML Service: http://localhost:63663/Service1.svc/GetCustomerListXML, and JSON Service: http://localhost:63663/Service1.svc/GetCustomerListJSON.
- Now, right-click on the project and select Add -> Service Reference as shown below:-
- Paste the wcf rest service URL (http://localhost:63663/Service1.svc) and click on the Go button to see a list of available services as shown below. All your available web methods (services) will appear on the pane below. Give specific reference namespace. Here I am giving the referenced namespace as “ServiceReference1”. Click on the Ok button to finish the Add service reference Wizard.
- After clicking on the Ok button a service model will generate in your web.config file as follows.
Now, find the below source code to consume wcf rest service c# json and XML format.

if (!IsPostBack)
{
ServiceReference1.Service1Client proxyClient = new ServiceReference1.Service1Client();
JavaScriptSerializer js = new JavaScriptSerializer();
object jsonResult = proxyClient.GetCustomerListJSON();
string strJSON = js.Serialize(jsonResult); // Converting object to JSON format string
grdDisplayJSON.DataSource = jsonResult;
grdDisplayJSON.DataBind();
object xmlResult = proxyClient.GetCustomerListXML();
grdDisplayXML.DataSource = xmlResult;
grdDisplayXML.DataBind();
}
}
catch (Exception ex)
{
throw ex;
}
}
}
}Output
