C# 试图用c语言获取twitter配置文件信息#

我正在尝试使用API调用检索经过身份验证的twitter用户的配置文件数据。我有一个用于此目的的特定方法，此时我只是尝试返回JSON字符串以验证它是否有效，但我得到一个400错误

public string getProfile(){
            // set your own keys and screen name

            var compositeKey = string.Concat(Uri.EscapeDataString(oauth_consumer_key),
                "&", Uri.EscapeDataString(oauth_token_secret));

            string oauth_signature;

对于authHeader，我的参数顺序错误：

var headerFormat = "OAuth oauth_consumer_key=\"{0}\", oauth_nonce=\"{1}\", " +
                               "oauth_signature=\"{2}\", oauth_signature_method=\"{3}\", " +
                               "oauth_timestamp=\"{4}\", oauth_token=\"{5}\", " +
                               "oauth_version=\"{6}\"";

            var authHeader = string.Format(headerFormat,
                Uri.EscapeDataString(oauth_nonce),
                Uri.EscapeDataString(oauth_signature_method),
                Uri.EscapeDataString(oauth_timestamp),
                Uri.EscapeDataString(oauth_consumer_key),
                Uri.EscapeDataString(oauth_token),
                Uri.EscapeDataString(oauth_signature),
                Uri.EscapeDataString(oauth_version)
            );

第五个参数是

oauth\u标记=\“{5}\”

和

oauth\u签名。那怎么可能呢？哦，除非你证明你的论点顺序不对。我的错。
