        m_resourceType       = location.ResourceType.ToString();
        m_hasDependencies    = location.HasDependencies;

        m_dependencies = location.Dependencies
                .Select( c => new ResourceLocationJsonData( c ) )
                .ToArray()
            ;
    }

    public string ToJson()
    {
        return JsonUtility.ToJson( this );
    }

    public string ToPrettyJson()
    {
        return JsonUtility.ToJson( this, true );
    }
}

使用例

private string InternalIdTransformFunc( IResourceLocation location )
{
    var jsonData = new ResourceLocationJsonData( location );
    Debug.Log( jsonData.ToPrettyJson() );
    return internalId;
}
