我的項目包含兩個部分「program.cs」和「Bitmex.cs」 我正在努力尋找如何將數據從「program.cs」發送到「Bitmex.cs」 。c＃將字符串數據發送到我的方法時的問題
在 「Program.cs的」 我有：
//data coming from websocket
dynamic socket = JsonConvert.DeserializeObject(e.Data);
object bid = socket["data"][0]["bidPrice"];
object plus = 1000.01;
double bida = Convert.ToDouble(bid);
double bidb = Convert.ToDouble(plus);
double sum = bida + bidb;
string sumB = sum.ToString();
Console.WriteLine(sumB);
bitmex.selllimit("10000", "1");
當我將數據發送到我的方法Bitmex.cs一切正常。
問題開始時我送這個（不工作）：
bitmex.selllimit(sumB, "1");
之間有什麼區別：（作品）
bitmex.selllimit(sumB, "1");
和：
bitmex.selllimit("10000", "1");
兩個是字符串不是嗎？
這是我在Bitmex.cs方法：
public string selllimit(string price,string volume)
{
var param = new Dictionary<string, string>();
param["symbol"] = "XBTUSD";
param["side"] = "Sell";
param["orderQty"] = volume;
param["price"] = price;
param["ordType"] = "Limit";
return Query("POST", "/order", param, true);
}
這裏bitmex API：

using System.Security.Cryptography;

using System.Threading;
namespace BitMEX
{

{
private const string domain = "https://www.bitmex.com";
private string apiKey;
private string apiSecret;
private int rateLimit;
public BitMEXApi(string bitmexKey = "", string bitmexSecret = "", int rateLimit = 5000)
{
this.apiKey = bitmexKey;
this.apiSecret = bitmexSecret;
this.rateLimit = rateLimit;
}
private string BuildQueryData(Dictionary<string, string> param)
{
if (param == null)
return "";
StringBuilder b = new StringBuilder();
foreach (var item in param)
b.Append(string.Format("&{0}={1}", item.Key, item.Value));
try { return b.ToString().Substring(1); }
catch (Exception) { return ""; }
}
public static string ByteArrayToString(byte[] ba)
{
StringBuilder hex = new StringBuilder(ba.Length * 2);
foreach (byte b in ba)
hex.AppendFormat("{0:x2}", b);
return hex.ToString();
}
private long GetNonce()
{
DateTime yearBegin = new DateTime(1990, 1, 1);
return DateTime.UtcNow.Ticks - yearBegin.Ticks;
}
private string Query(string method, string function, Dictionary<string, string> param = null, bool auth = false)
{
string paramData = BuildQueryData(param);
string url = "/api/v1" + function + ((method == "GET" && paramData != "") ? "?" + paramData : "");
string postData = (method != "GET") ? paramData : "";
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(domain + url);
webRequest.Method = method;
if (auth)
{
string nonce = GetNonce().ToString();
string message = method + url + nonce + postData;
byte[] signatureBytes = hmacsha256(Encoding.UTF8.GetBytes(apiSecret), Encoding.UTF8.GetBytes(message));
string signatureString = ByteArrayToString(signatureBytes);
webRequest.Headers.Add("api-nonce", nonce);
webRequest.Headers.Add("api-key", apiKey);
webRequest.Headers.Add("api-signature", signatureString);
}
try
{
if (postData != "")
{
webRequest.ContentType = "application/x-www-form-urlencoded";

感謝您的幫助
什麼錯誤，你得到一個字符串？ –
「Console.WriteLine（sumB）;'顯示的行是什麼？ – Fabulous
