    GetVersionManager Method
    In This Topic
    Gets the VersionManager associated with this geodatabase if it supports versioning. This method must be called on the MCT. Use QueuedTask.Run.
    Syntax
    public VersionManager GetVersionManager()
    Public Function GetVersionManager() As VersionManager

    Return Value

    The VersionManager associated with this geodatabase if it supports versioning.
    Exceptions
    ExceptionDescription
    This geodatabase does not support versioning.
    Remarks
    If IsVersioningSupported returns false, calling this method will result in an exception.
    Example
    Connecting to a Version
    public Geodatabase ConnectToVersion(Geodatabase geodatabase, string versionName)
    {
      Geodatabase connectedVersion = null;
    
      if (geodatabase.IsVersioningSupported())
      {
        using (VersionManager versionManager = geodatabase.GetVersionManager())
        using (Version version = versionManager.GetVersion(versionName))
        {
          connectedVersion = version.Connect();
        }
      }
      return connectedVersion;
    }
    Working with Versions
    public async Task WorkingWithVersions()
    {
      await ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() =>
      {
        using (Geodatabase geodatabase = new Geodatabase(new DatabaseConnectionFile(new Uri("path\\to\\sde\\file"))))
        using (VersionManager versionManager = geodatabase.GetVersionManager())
        {
          IReadOnlyList<Version> versionList = versionManager.GetVersions();
    
          Version defaultVersion = versionManager.GetDefaultVersion();
    
          IEnumerable<Version> publicVersions = versionList.Where(
            version => version.GetAccessType() == VersionAccessType.Public);
          Version qaVersion = defaultVersion.GetChildren().First(
            version => version.GetName().Contains("QA"));
    
          Geodatabase qaVersionGeodatabase = qaVersion.Connect();
    
          FeatureClass currentFeatureClass = geodatabase.OpenDataset<FeatureClass>("featureClassName");
          FeatureClass qaFeatureClass = qaVersionGeodatabase.OpenDataset<FeatureClass>("featureClassName");
        }
      });
    }
    Working with the Default Version
    // Check to see if the current version is default.
    // Works with both branch and traditional versioning.
    public bool IsDefaultVersion(Version version)
    {
      Version parentVersion = version.GetParent();
      if (parentVersion == null)
      {
        return true;
      }
      parentVersion.Dispose();
      return false;
    }
    
    public bool IsDefaultVersion(Geodatabase geodatabase)
    {
      if (!geodatabase.IsVersioningSupported()) return false;
      using (VersionManager versionManager = geodatabase.GetVersionManager())
      using (Version currentVersion = versionManager.GetCurrentVersion())
      {
        return IsDefaultVersion(currentVersion);
      }
    }
    
    // Gets the default version.
    // Works with both branch and traditional versioning.
    // Note that this routine depends on IsDefaultVersion(), above.
    public Version GetDefaultVersion(Version version)
    {
      if (IsDefaultVersion(version))
      {
        return version;
      }
      else
      {
        Version parent = version.GetParent();
        Version ancestor = GetDefaultVersion(parent);
        if (parent != ancestor)
        {
          parent.Dispose(); //If the versioning tree is more than 2 deep, we want to dispose any intermediary versions
        }
        return ancestor;
      }
    }
    
    public Version GetDefaultVersion(Geodatabase geodatabase)
    {
      if (!geodatabase.IsVersioningSupported()) return null;
    
      using (VersionManager versionManager = geodatabase.GetVersionManager())
      {

        Version defaultVersion = GetDefaultVersion(currentVersion);
        if (currentVersion != defaultVersion)
        {
          currentVersion.Dispose(); // If we are not pointing to default, we want to dispose this Version object
        }
