Hi,

i am using webapi and I am stuck in how to pass parameter in header and querystring single time.

Can you help me please .

Look at below code.

HttpClient client = new HttpClient();

client.DefaultRequestHeaders.Add("para1", "para1");

client.DefaultRequestHeaders.Add("para2", "para2");

HttpResponseMessage response1 = client.GetAsync("https://test.com/api/[email protected]").Result;

if (response1.IsSuccessStatusCode)

{

var result = response1.Content.ReadAsStringAsync().Result;

}

else

{

//Something has gone wrong, handle it here

}

Please help me

Thanks in advance.

Try this sample code:
using(var client = newHttpClient())
{
    client.BaseAddress = newUri("http://localhost:55587/");
    client.DefaultRequestHeaders.Accept.Clear();
    client.DefaultRequestHeaders.Add("User-Agent", "C# console program"); //Header Data
    client.DefaultRequestHeaders.Add("Param1", "KayValue"); //Header Data
    client.DefaultRequestHeaders.Accept.Add(newMediaTypeWithQualityHeaderValue("application/json"));

    var _Body = newDepartment() { DepartmentName = "Test Department" };  //Query
   // Another way to pass data: HttpContent _Body = new StringContent(Body);
    HttpResponseMessage response = awaitclient.PostAsync("api/Department", _Body);
    response.EnsureSuccessStatusCode();

    if (response.IsSuccessStatusCode)
     {
       var resp = await response.Content.ReadAsStringAsync();
     }
}

Updated for your case:
using(var client = newHttpClient())
{
    client.BaseAddress = newUri("https://test.com/");
    client.DefaultRequestHeaders.Accept.Clear();
    client.DefaultRequestHeaders.Add("User-Agent", "C# console program"); //Header Data
    client.DefaultRequestHeaders.Add("Param1", "KayValue"); //Header Data
    client.DefaultRequestHeaders.Accept.Add(newMediaTypeWithQualityHeaderValue("application/json"));

    //var _Body = newDepartment() { DepartmentName = "Test Department" };  //Query: No need for Get Method
   // Another way to pass data: HttpContent _Body = new StringContent(Body);
    HttpResponseMessage response = awaitclient.GetAsync("api/Departmentapi/[email protected]");
    response.EnsureSuccessStatusCode();

    if (response.IsSuccessStatusCode)
     {
       var resp = await response.Content.ReadAsStringAsync();
     }
}
