Pass two JSON object by web client post method C#

Question

I need to pass below object as a parameter for a post method using web client method in C#.

     {
    "company":
    {
        "id": "e63dfcab345260b2591f585126ede56627db4ef2"
    },
    "requestor":
    {
        "id": "",
        "email": "customer@example.com ",
        "firstName": "Test",
        "lastName": "Requestor",
        "role": "employerAdmin",
        "phone": "(415)1112222",
        "title": "HR Manager"
    }
}

I converted like this

company[id]=e63dfcab345260b2591f585126ede56627db4ef2&requestor[id]=&requestor[email]=customer@example.com+&requestor[firstName]=Test&requestor[lastName]=Requestor&requestor[role]=employerAdmin&requestor[phone]=(415)1112222&requestor[title]=HR+Manager

But i am getting invalid parameter error. Please help me. Thanks in advance.

My entire code is below:

 using (var Requestor = new System.Net.WebClient())
            {

                string url = "https://stormaas-pre.inflection.com:8443/v1/Requestor?";
                string parameters = "company[id]='757563a3-67df-4a6e-9ef9-d89d57d41e0d'&requestor[id]=''&requestor[email]='customer@example.com'&requestor[firstName]='Test'&requestor[lastName]='Requestor'&requestor[role]='employerAdmin'&requestor[phone]='(415)1112222'&requestor[title]='HRManager'";
                Requestor.Headers.Add("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)");
                Requestor.Credentials = new System.Net.NetworkCredential("xyz:xyz!", "");
                Requestor.Encoding = System.Text.Encoding.UTF8;
                Requestor.Headers[HttpRequestHeader.ContentType] = "application/json";
                Requestor.Headers[HttpRequestHeader.Accept] = "text/xml";
                string res = Requestor.UploadString(url, "POST", parameters);
            }

Answer 1

You can create POCO classes for the Requestor, Company like follows and use JSON.net to do the conversion for you.

public class Company
{
    public string Id { get; set; }
    // Other properties
}

public class Requestor
{
    public string Id { get; set; }

    public string Email { get; set; }

    public string FirstName { get; set; }

    public string LastName { get; set; }
    // Other properties
}

public class Container
{
    public Company Company { get; set; }

    public Requestor Requestor { get; set; }
}

var requestor = new Container();
requestor.Company = new Company { Id = "sampleid" };
requestor.Requestor = new Requestor
{
    FirstName = "test",
    LastName = "testname"
};

JsonSerializerSettings settings = new JsonSerializerSettings();
settings.ContractResolver = new CamelCasePropertyNamesContractResolver();
var data = JsonConvert.SerializeObject(requestor, settings);

WebClient client = new WebClient();
client.Headers.Add(HttpRequestHeader.ContentType, "application/json");
// Code for the credentials etc
client.UploadString(@"your url", data);

Hope this helps. For this to work, you need to have a reference to JSON.net. Since you are using .net 4.5 with Web API, you should be having the reference already.

You get invalid parameter error because square bracket are not allowed in a url. If you want use characters that are not include in RFC 1738 you must use HttpUtility.UrlEncode("String")(msdn reference)
