C# 在LinkedIn中发布状态

我看到一篇文章，介绍了如何使用c#在LinkedIn中分享我们的状态。
我遵循这些步骤，我使用的代码如下…
为此，我使用吊床图书馆

        OAuthCredentials credentials = new OAuthCredentials();

        credentials.Type = OAuthType.AccessToken;
        credentials.ConsumerKey = "****";
        credentials.ConsumerSecret = "*****";
        credentials.Token = "******";
        credentials.TokenSecret = "*********";
        credentials.SignatureMethod = OAuthSignatureMethod.HmacSha1;
        credentials.ParameterHandling = OAuthParameterHandling.HttpAuthorizationHeader;


        RestClient client = new RestClient();

        client.Authority = "http://api.linkedin.com/v1";
        client.Credentials = credentials;
        client.Method = WebMethod.Put;
        byte[] msg = Encoding.Default.GetBytes("Test");
        client.AddHeader("Content-Type", "text/xml");
        client.AddPostContent(msg);


        RestRequest request = new RestRequest();
        request.Path = "http://api.linkedin.com/v1/people/~/current-status";


 /* ERROR */ RestResponse response = client.Request(request);

它给了我一个错误“错误的请求”

如何解决此问题，请帮助我？

@SearchAndResQ-Ya我尝试过，但它给出了错误“找不到方法”
