    Example
    Creating a feature class
    public void CreateFeatureClassSnippet(Geodatabase geodatabase, FeatureClass existingFeatureClass, SpatialReference spatialReference)
    {
      // Create a Cities feature class with the following fields
      //  GlobalID
      //  ObjectID
      //  Name (string)
      //  Population (integer)
    
      // This static helper routine creates a FieldDescription for a GlobalID field with default values
      FieldDescription globalIDFieldDescription = FieldDescription.CreateGlobalIDField();
    
      // This static helper routine creates a FieldDescription for an ObjectID field with default values
      FieldDescription objectIDFieldDescription = FieldDescription.CreateObjectIDField();
    
      // This static helper routine creates a FieldDescription for a string field
      FieldDescription nameFieldDescription = FieldDescription.CreateStringField("Name", 255);
    
      // This static helper routine creates a FieldDescription for an integer field
      FieldDescription populationFieldDescription = FieldDescription.CreateIntegerField("Population");
    
      // Assemble a list of all of our field descriptions
      List<FieldDescription> fieldDescriptions = new List<FieldDescription>()
        { globalIDFieldDescription, objectIDFieldDescription, nameFieldDescription, populationFieldDescription };
    
      // Create a ShapeDescription object
      ShapeDescription shapeDescription = new ShapeDescription(GeometryType.Point, spatialReference);
    
      // Alternatively, ShapeDescriptions can be created from another feature class.  In this case, the new feature class will inherit the same shape properties of the existing class
      ShapeDescription alternativeShapeDescription = new ShapeDescription(existingFeatureClass.GetDefinition());
    
      // Create a FeatureClassDescription object to describe the feature class to create
      FeatureClassDescription featureClassDescription =
        new FeatureClassDescription("Cities", fieldDescriptions, shapeDescription);
    
      // Create a SchemaBuilder object
      SchemaBuilder schemaBuilder = new SchemaBuilder(geodatabase);
    
      // Add the creation of the Cities feature class to our list of DDL tasks
      schemaBuilder.Create(featureClassDescription);
    
      // Execute the DDL
      bool success = schemaBuilder.Build();
    
      // Inspect error messages
      if (!success)
      {
        IReadOnlyList<string> errorMessages = schemaBuilder.ErrorMessages;
        //etc.
