public HttpResponseMessage MakePostAsync()
{
    string apiUrl = "https://abc.c9api.in/api/method/upload_file";
    var client = new HttpClient();
    var request = new HttpRequestMessage(HttpMethod.Post, apiUrl);
    string filepath = @"C:\Users\Javed.shaikh\Desktop\CSVFiles\SalesOrderDetail.csv";

    client.DefaultRequestHeaders.Add("Authorization", "Token f802cc75fabec4770:62fa1ba5aff78bbfc4d");
    content.Add(new StringContent("0"), "is_private");
    content.Add(new StringContent("Home"), "folder");
    var fileContent = new StreamContent(new FileStream(filepath, FileMode.Open));
    fileContent.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("multipart/form-data");
    fileContent.Headers.ContentDisposition = new ContentDispositionHeaderValue("form-data")
    {
        Name = "file",
        FileName = "SalesOrderDetail.csv"
    };
    content.Add(fileContent);
    request.Content = content;
    Task<HttpResponseMessage> result = client.SendAsync(request);

        Content = new StringContent("Response: ", System.Text.Encoding.UTF8, "application/json"),
        StatusCode = HttpStatusCode.OK
    };
