How To Call WCF Service Method From PostMan In C#

Calling a WCF service method from Postman in C#

we can do that this by following these steps:

1. We need to know the URL of the service endpoint that we want to call. This URL typically looks like http://localhost:5572/Product/Service.svc and now open Postman and create a new request of type POST. In the request URL, paste the service endpoint URL.
2. Set Headers: If the service requires any specific headers (like authentication tokens or content type), we should add them to the request. This can typically be done in the Headers section of the Postman request.
3. If the service method expects any data in the request body, we should add it in the Body section of the Postman request. This can be in JSON format, XML, or any other format that the service expects.

Now, let's see an example of how we can call a WCF service method from C# code:

using System;
using System.Net.Http;
using System.Threading.Tasks;

public class Program
{
    public static async Task Main(string[] args)
    {
        // Define the URL of the WCF service endpoint
        string serviceUrl = "http://localhost:5572/Product/Service.svc";

        // Create an instance of HttpClient
        using (HttpClient client = new HttpClient())
        {
            try
            {
                // Prepare data if needed
                string requestData = "{\"Name\":\"Phone\", \"Price\":\"122\"}";

                // Create a StringContent object with request data
                var content = new StringContent(requestData, System.Text.Encoding.UTF8, "application/json");

                // Send a POST request to the service endpoint
                HttpResponseMessage response = await client.PostAsync(serviceUrl, content);

                // Check if the request was successful
                if (response.IsSuccessStatusCode)
                {
                    // Read the response content
                    string responseContent = await response.Content.ReadAsStringAsync();

                    // Output the response
                    Console.WriteLine("Response from service: " + responseContent);
                }
                else
                {
                    // Output the error message
                    Console.WriteLine("Error: " + response.ReasonPhrase);
                }
            }
            catch (Exception ex)
            {
                // Handle any exceptions
                Console.WriteLine("Exception: " + ex.Message);
            }
        }
    }
}
