I can't get a soap message in C#

I'm getting an error:
A security error was encountered when verifying the message
Https is expected when I somehow overcome this error. But I have to use Http.
EndpointAddress address2 = new EndpointAddress("http://xx.xx.xxxx/ws/test?wsdl");
FactoryWebServiceClient client = new FactoryWebServiceClient();
client.Endpoint.Address = address2;
if (client.ClientCredentials != null)
{
client.ClientCredentials.Windows.ClientCredential = new System.Net.NetworkCredential("username","password");
client.ClientCredentials.UserName.UserName = "username";
client.ClientCredentials.UserName.Password = "password";
}
XmlDocument doc = new XmlDocument();
doc.Load("C:\\...\\test.xml");
byte[] bytes = Encoding.Default.GetBytes(doc.OuterXml);
var request2 = new factoryWSUpdateData
{
BeanXml = bytes,
Period = 1,
InputType = "xml",
OutputType = "json2",
CodeTemplate = 1
};
var result = client.create(request2);

Yahoo Weather API using Oauth

I am stuck on implementing the Yahoo Weather private API call. This is my code snippet, whenever I call it using valid clientId & Secret it returns 401 (unauthorized).
var outhWc = new WebClient();
outhWc.Credentials = new NetworkCredential(clientId, clientSecret);
outhWc.Headers.Add(HttpRequestHeader.Accept, "application/json");
var outhresponse = outhWc.DownloadData("https://query.yahooapis.com/v1/yql?q=select%20*%20from%20weather.forecast%20where%20woeid%20in%20(select%20woeid%20from%20geo.places(1)%20where%20text%3D%22nome%2C%20ak%22)&format=json");
It always throws an exception. I also try to pass username and password in NetworkCredentials and also try to pass clientId and Secret in Header but I cannot find a successful call.

So I've been stuck with the same issue here. Finally I implemented the following code, based on the oAuth c# simple class found at http://oauth.googlecode.com/svn/code/csharp/OAuthBase.cs
public void LoadWeather() {
string URLDes, Params = "";
string Signature, BaseURL, cKey, cSecret = "";
OAuthBase oAuth = new OAuthBase();
BaseURL = "http://weather.yahooapis.com/forecastrss?w=" + textBox1.Text + "&u=f";
cKey = "YOUR API KEY";
cSecret = "YOUR API SECRET";
Signature = oAuth.GenerateSignature(new Uri(BaseURL), cKey, cSecret, "", "", "GET", oAuth.GenerateTimeStamp(), oAuth.GenerateNonce(), out URLDes, out Params);
WebClient wc = new WebClient();
wc.DownloadStringCompleted += HttpsCompleted;
wc.DownloadStringAsync(new Uri(String.Format("{0}?{1}&oauth_signature={2}", URLDes, Params, Signature)));
}
private void HttpsCompleted(object sender, DownloadStringCompletedEventArgs e) {
if (e.Error == null) {
XDocument xdoc = XDocument.Parse(e.Result, LoadOptions.None);
xdoc.Save("c:\\weather.xml");
richTextBox1.Text = xdoc.FirstNode.ToString();
} else {
richTextBox1.Text = e.Error.Message;
}
}
As you can see, I already have the city ID. This sample downloads the xml string returned by the API. Worked for me, hope it helps!

HTTP POST is giving unauthorized 401 Exception

When calling the same method on google chrome postman after logging in, i'm getting the json object as shown below.
but when i try to get the same json result in codebehind (C#). I'm getting Unauthorized 401 exception.
I'm using my code like this.
using (var clientSideTab = new WebClient())
{
var valSideTab = new System.Collections.Specialized.NameValueCollection { { "username", UserID }, { "Password", strPassword } };
string UpldDataSideTab = "https://resapistage.namechanged.com/v3/secure/Login.aspx?userId=" + UserID + "&passwd=" + strPassword + " ";
SystemComponentWrapper SPPostWrapper = new SystemComponentWrapper();
SystemComponentData request = new SystemComponentData();
SystemComponentaddressId addressId = new SystemComponentaddressId();
addressId.type = "AddressId";
addressId.id = 19863;
addressId.serial = "";
request.addressId = addressId;
request.compId = null;
request.getCompParams = true;
request.filterForAddress = false;
SPPostWrapper.request = request;
var postJson = JsonConvert.SerializeObject(SPPostWrapper);
Encoding encoding = new UTF8Encoding();
string postData = postJson.ToString();
byte[] bdata = encoding.GetBytes(postData);
string URI = "https://resapistage.namechanged.com/v3/api/secure/json/AddressInfo.svc/getSystemComponentsV2";
clientSideTab.UploadValues(UpldDataSideTab, "POST", valSideTab);
clientSideTab.Headers.Add("Content-Type","application/json; charset=utf-8");
clientSideTab.Headers.Add("Accept","application/json");
clientSideTab.UploadString(URI,"POST", postData);
//clientSideTab.UploadData(URI, "POST", bdata);
String jsonresponse = "failed";
Label1.Text = jsonresponse;
}
I'm getting this error everytime. please help me.

use like this.
string cookie = strCookie[0]; // fetch your cookie after logging in
clientSideTab.Headers.Add("Content-Type","application/json; charset=utf-8");
clientSideTab.Headers.Add("Accept","application/json");
clientSideTab.m_container.SetCookies(URI, cookie);
//clientSideTab.Headers.Add(HttpRequestHeader.Cookie, cookie);
String resultJSON = clientSideTab.UploadString(URI,"POST", jsonData);
this worked for me. hope this will help you.

byte[] databytes = Encoding.UTF8.GetBytes(data);
var request = new RestRequest { Path = "comments" };
var credentials = new Hammock.Authentication.OAuth.OAuthCredentials
{
Type = OAuthType.AccessToken,
SignatureMethod = OAuthSignatureMethod.HmacSha1,
ParameterHandling = OAuthParameterHandling.HttpAuthorizationHeader,
