StockSharp.Configuration

StockSharp.Configuration is a .NET Standard library that centralizes various configuration facilities used by the StockSharp trading platform. It provides classes for storing application paths, loading settings, managing user credentials, and constructing message adapters. The assembly is titled S#.Configuration and described as "Configuration components."

Features

• System paths – the Paths class defines all important directories and files used by StockSharp. Paths are initialized from PathsHolder and configuration files, as shown below:

  var companyPath = PathsHolder.CompanyPath ?? ConfigManager.TryGet<string>("companyPath");
  CompanyPath = companyPath.IsEmpty() ? Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments), "StockSharp") : companyPath.ToFullPathIfNeed();
  CredentialsFile = Path.Combine(CompanyPath, $"credentials{DefaultSettingsExt}");
  PlatformConfigurationFile = Path.Combine(AppDataPath, $"platform_config{DefaultSettingsExt}");

• Start‑up settings – AppStartSettings stores language preference and online/offline mode and can be loaded or saved from the platform configuration file:

  public class AppStartSettings : IPersistable
  {
      public string Language { get; set; } = LocalizedStrings.ActiveLanguage;
      public bool Online { get; set; } = true;
      public static AppStartSettings TryLoad()
      {
          var configFile = Paths.PlatformConfigurationFile;
          if (configFile.IsEmptyOrWhiteSpace() || !configFile.IsConfigExists())
              return null;
          return configFile.Deserialize<SettingsStorage>()?.Load<AppStartSettings>();
      }
  }

  【F:Configuration/AppStartSettings.cs†L4-L41】
• Credentials management – the ICredentialsProvider interface allows loading, saving and deleting of ServerCredentials. The default implementation persists credentials in Paths.CredentialsFile:

  public interface ICredentialsProvider
  {
      bool TryLoad(out ServerCredentials credentials);
      void Save(ServerCredentials credentials, bool keepSecret);
      void Delete();
  }

  【F:Configuration/ICredentialsProvider.cs†L4-L25】

  class DefaultCredentialsProvider : ICredentialsProvider
  {

• private readonly Lock _lock = new();
  private ServerCredentials _credentials;
  bool ICredentialsProvider.TryLoad(out ServerCredentials credentials)
  {
      using (_lock.EnterScope())
      {
          if(_credentials != null)
          {
              credentials = _credentials.Clone();
              return credentials.CanAutoLogin();
          }
          var file = Paths.CredentialsFile;
          credentials = null;
          if (file.IsConfigExists())
          {
              credentials = new ServerCredentials();
              credentials.LoadIfNotNull(file.Deserialize<SettingsStorage>());
              _credentials = credentials.Clone();
          }
          return credentials?.CanAutoLogin() == true;
      }
  }
  

  }

  【F:Configuration/DefaultCredentialsProvider.cs†L3-L38】
  

• Invariant serialization – InvariantCultureSerializer saves configuration files using the invariant culture and UTF‑8 encoding, enabling culture‑independent settings:

  public static class InvariantCultureSerializer
  {
      public static void SerializeInvariant(this SettingsStorage settings, string fileName, bool bom = true)
      {
          if (settings is null)
              throw new ArgumentNullException(nameof(settings));
          Do.Invariant(() => settings.Serialize(fileName, bom));
      }
  }

  【F:Configuration/InvariantCultureSerializer.cs†L3-L23】
• Message adapter discovery – InMemoryMessageAdapterProvider scans all local assemblies for IMessageAdapter implementations and can create adapters on demand:

  public class InMemoryMessageAdapterProvider : IMessageAdapterProvider
  {
      public InMemoryMessageAdapterProvider(IEnumerable<IMessageAdapter> currentAdapters, Type transportAdapter = null)
      {
          CurrentAdapters = currentAdapters ?? throw new ArgumentNullException(nameof(currentAdapters));
          var idGenerator = new IncrementalIdGenerator();
          PossibleAdapters = [.. GetAdapters().Select(t =>
          {
              try
              {
                  return t.CreateAdapter(idGenerator);
              }
              catch (Exception ex)
              {
                  ex.LogError();
                  return null;
              }
          }).WhereNotNull()];
      }
  }

  【F:Configuration/InMemoryMessageAdapterProvider.cs†L5-L51】
• Utility helpers – the Paths class also exposes methods for serialization, backup management and building links to StockSharp documentation and store pages.

Usage

1. Configure global paths before accessing Paths by setting PathsHolder.CompanyPath and PathsHolder.AppDataPath if your application uses custom directories.
2. Load or create application start settings with AppStartSettings.TryLoad and save them using TrySave.
3. Implement ICredentialsProvider or use DefaultCredentialsProvider to persist server credentials securely.
4. Use InvariantCultureSerializer when you need stable serialization irrespective of system locale.
5. Create an instance of InMemoryMessageAdapterProvider to dynamically discover available message adapters.
