Data type mapping for C# (C# code)
For each Data Type that is not nested, ACS generates a code file (.cs) unless the tagged value of the C# Parent File Scoped tag definition is set to True. Within the code file, ACS generates the Data Type as a struct.
The struct declaration and body is derived from the items it owns, properties of the Data Type, and the tagged values set for Tag Definitions applied by the «C# Classifier» stereotype.
ACS generates the child items, properties and tagged values of a Data Type as follows.
Child items:
• If the Data Type owns any Attributes, ACS generates each Attribute as a constant, event, field or property. For more information about Attribute mapping, click here Attribute mapping.
• If the Data Type owns any Operations, ACS generates each Operation as a constructor, delegate, finalizer, indexer, method or operator. For more information about Operation mapping, click here Operation mapping
• If the Data Type owns any Roles, ACS generates the each Role as a constant, field or property. For more information about Role mapping, click here Association mapping
Other child items are ignored.
Properties:
• If a Description is specified, ACS generates the text of a Data Type's Description property on the line before the code generated for the struct. For information about how comments are generated, click here Generating code comments
• ACS generates the Name property as the identifier of the struct.
* 
ACS may modify the struct identifier that is added to the code to make it valid for C#. You can specify the exact identifier to use through the CODE_GENERATION_NAME property of a Data Type. Tell me more...
• If the Template property is set to True (Template check box selected on Property Pages), ACS generates the Data Type as a generic struct. ACS generates the Formal Template Parameters as the type parameters between angle brackets after the struct identifier.
• If the Visibility property is set to public, private or protected: ACS generates the struct with a public, private or protected modifier accordingly – ACS generates private and protected modifiers only for nested Data Type.
• If the Visibility property is set to public or package: ACS generates the struct with a public or internal modifier accordingly – ACS generates private and protected modifiers only for nested structs.
Other properties are ignored.
Tag Definitions:
The «C# Classifier» stereotype applies the following Tag Definitions to a Data Type:
• If a value is set for the tagged value of the C# Attributes tag definition, ACS generates the value as the set of attributes for the struct.
• If a value is set for the tagged value of the C# Extern Alias Directives tag definition and the Data Type is generated as a compilation unit, ACS generates the value as the external alias directives. Use this tag definition when defining directives for a Data Type that cannot be modeled within the model.
• The tagged value of the read-only C# File tag definition is used for opening generated code files from Modeler. This value is set by ACS.
* 
The tagged value of the derived C# File tag definition is stored in your computer's registry (not the model) – the path and file name you see does not apply to other users of the model.
• If the tagged value of the C# Internal tag definition is set to Internal, ACS generates the struct with the internal modifier.
If the Data Type is a child of a Class and the C# Internal tag definition is set to Protected Internal, ACS generates the struct with the protected internal modifiers.
• If the tagged value of the C# New tag definition is set to True, ACS generates the new keyword when appropriate.
• If the tagged value of the C# Parent File Scoped tag definition is set to True, ACS does not generate a code file for the Data Type and the struct is defined in the code file that is generated for the owning Model, Package or Class.
• If the tagged value of the C# Partial tag definition is set to True - ACS generates the struct with the Partial modifier.
• The C# Sealed tag definition is not used when applied to a Data Type.
• The C# Static tag definition is not used when applied to a Data Type.
• If the Data Type is a template class (generates a generic type - see Template property) and a value is set for the tagged value of the C# Type Parameters Constraints tag definition, ACS generates the value as the constraints that apply to the type parameters of a generic type. ACS generates the value after the struct declaration and before the body code.
• If the tagged value of the C# Unsafe tag definition is set to True, ACS generates the struct with the Unsafe modifier.
• If a value is set for the tagged value of the C# Using Directives tag definition, ACS generates the value as the using directives of the struct.
ACS generates the using directives that are required for the code it generates; however, should you require additional using directives that cannot be derived from the model, use the C# Using Directives to specify them.
