使用DotNetOpenAuth时出现400错误的请求

Question

I am using DotNetOpenAuth to implement OAuth in my local system. Everytime I am getting the following error : +

ex.InnerException   {"The remote server returned an error: (400) Bad Request."} System.Exception {System.Net.WebException}

Below is my code snippet

  AuthorizationServerDescription authServer = new AuthorizationServerDescription()
{
    TokenEndpoint = new Uri(TOKEN_ENDPOINT),
    AuthorizationEndpoint = new Uri(AUTHZ_ENDPOINT),
};

                string[] scopes = new string[] { "Scope" };
                var client = new WebServerClient(authServer , "ClientId", "Client_Secret");


                var token= client.ExchangeUserCredentialForToken("username", "password");

When client.ExchangeUserCredentialForToken is called then I am getting error. Couldn't figure out what wrong is happening. What can be the potential reason?

您未在请求中提供范围，请尝试在最后一个参数中添加范围：

client.ExchangeUserCredentialForToken("username", "password", scopes);
