我从这里下载比特币核心https://bitcoin.org/en/download并尝试从C#连接到它我使用这里的演示代码
https://github.com/cryptean/bitcoinlib
我这样设置bitcoin.conf：
server=1
rpcport=8332
rpcuser=myuser
rpcpass=mypass
txindex=1
这是app.config：
<!-- Bitcoin settings start -->
<add key="Bitcoin_DaemonUrl" value="http://127.0.0.1:8332" />
<add key="Bitcoin_DaemonUrl_Testnet" value="http://127.0.0.1:18332" />
<add key="Bitcoin_WalletPassword" value="" />
<add key="Bitcoin_RpcUsername" value="myuser" />
<add key="Bitcoin_RpcPassword" value="mypass" />
<!-- Bitcoin settings end -->
当我运行演示时，发生了错误，这是错误消息：

foreach (var parameter in parameters)

}
joe.Add(new JProperty("params", props));
// serialize json for the request
string s = JsonConvert.SerializeObject(joe);
byte[] byteArray = Encoding.UTF8.GetBytes(s);
webRequest.ContentLength = byteArray.Length;
Stream dataStream = webRequest.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close();
StreamReader streamReader = null;
try
{
WebResponse webResponse = webRequest.GetResponse();
streamReader = new StreamReader(webResponse.GetResponseStream(), true);

var data = JsonConvert.DeserializeObject(respVal).ToString();
return data;
}
catch (Exception exp)
{
Console.WriteLine(exp.Message + "\n" + exp.StackTrace.ToString());

finally
{
if (streamReader != null)
{
streamReader.Close();
}
}
return string.Empty;
}
var data = RequestServer("getblockcount", new List<string>() { "value" });
Console.WriteLine(data);
但是发生了错误：

我还阅读了有关此库的信息NBitcoin，但我找不到如何使用它的简单示例。我的问题：从 C# 连接比特币核心的步骤是什么，使用它的最佳库是什么？如何修复我上面提到的这些错误？有使用 NBitcoin 的简单示例吗？谢谢。
一个小错误，bitcoin.conf 中的单词：
rpcpass=mypass
错了一定是:
rpcpassword=mypass
我改变了它，效果很好
