Get a list of field types

This is an example that gets the field types and the number of data points for reference fields from the model selected in the editor.

public void OutputFields(ICommandContext c, ICommandParams p) 
{ 
//Get the first model selected in the model editor 
var model = c.App.Window.EditorPage.CurrentEditorView.SelectedModels.FirstOrDefault(); 
if (model == null) { 
c.App.Window.UI.ShowMessageBox("Please select one target model in the model editor"); 
return; 
} 

c.App.Output.WriteLine("Default", $"Model name: {model.Name}, Metamodel name: {model.Metaclass.DisplayName}({model.Metaclass.Name})"); 

//Get the field and its type name of the target model 
//For reference fields, get the number of reference data as well 
var fields = model.Metaclass.GetFields(); //IFieldCollection type 

foreach (var field in fields) 
{ 
if (field.Name.StartsWith("___")) 
{ 
//Ignore system fields 
continue; 
} 

c.App.Output.WriteLine("Default", $" Field: {field.DisplayName}({field.Name}), <Type name: {field.Type}>"); 
if (field.TypeClass != null) 
{ 
c.App.Output.WriteLine("Default", $" Number of reference data: {model.GetFieldValues(field.Name).Count}"); 
} 
} 
} 

Note

When retrieving fields using the API, system-defined fields can also be retrieved at the same time. System-defined fields follow the following rules, so exclude them if you do not need them.

• The name (IField.Name) is prefixed with "$"
• The name (IField.Name) is prefixed with "___"
