C#

To define C# as the target language in a template file :

#set( $env.language = 'C#' )

A "?" is automatically added to the end of the type if the attribute is "nullable" (no "@NotNull" annotation). To disable this behavior:

#set( $env.typeWithNullableMark = false )

The information below shows the behavior of the generator when C# is the current target language. For a detailed description of type conversion, see the generated documentation : https://www.telosys.org/doc/latest/languages/language-csharp.html

Types conversion

The table below describes how model neutral types are automatically converted to C# types with potential impact due to attribute annotations.

Model type	C# type	with annotation
string	string? string String?	@NotNull @ObjectType
byte	sbyte? sbyte byte? SByte?	@NotNull @UnsignedType @ObjectType
short	short? short ushort? Int16?	@NotNull @UnsignedType @ObjectType
int	int? int uint? Int32?	@NotNull @UnsignedType @ObjectType
long	long? long ulong? Int64?	@NotNull @UnsignedType @ObjectType
decimal	decimal? decimal Decimal?	@NotNull @ObjectType
float	float? float Single?	@NotNull @ObjectType
double	double? double Double?	@NotNull @ObjectType
boolean	bool? bool Boolean?	@NotNull @ObjectType
date	DateOnly? DateOnly	@NotNull
time	TimeOnly? TimeOnly	@NotNull
timestamp	DateTime? DateTime	@NotNull
binary	byte[]? byte [ ]	@NotNull

Remarks:

• since ver 4.1.0 "date" is converted to "DateOnly" and "time" is converted to "TimeOnly"

Annotations effects

• @UnsignedType has effect only for byte, short, int, long

• @ObjectType switches to .Net types ( System.Int64, System.Boolean, etc)

• @NotNull type not nullable => no "?" at the end of the type

• @PrimitiveType no effect

Specific types

• $attribute.fullType returns the C# System class full name for both "primitive type" and "object type" ( for example : System.String, System.Int16, System.Decimal )

• $attribute.simpleType

  • for an "object type" returns the simple type name of the C# System class ( for example : String, Int16, Decimal )

  • for a "standard type" returns the usual type ( for example : string, int, uint, bool )

• $attribute.wrapperType returns the C# System class associtated with the curren type

Literal values

TRUE, FALSE, NULL

	C# literal
TRUE	true
FALSE	false
NULL	null

Generated literal values

Below some examples of literal values generated for each type :

Model type	C# type	C# literal value
string	string System.String	"AAA"
byte	sbyte byte System.SByte	1
short	short ushort System.Int16	1
int	int uint System.Int32	100
long	long ulong System.Int64	1000L
decimal	decimal System.Decimal	10000.77M
float	float System.Single	1000.5F
double	double System.Double	1000.66D
boolean	bool System.Boolean	true or false
date	System.DateOnly	null
time	System.TimeOnly	null
timestamp	System.DateTime	null
binary	byte [ ]	null
