Type support

Synopsis

#include <metadata/metadata.h> #include <metadata/class.h> typedef struct _MonoType MonoType;

The MonoType represents the unmanaged version of System.Type.

mono_type_get_object
Syntax
MonoReflectionType* mono_type_get_object (MonoDomain *domain, MonoType *type)

Parameters
domain an app domain
type a type
Return value
A System.MonoType object representing the type type.
mono_type_create_from_typespec

Deprecated: use mono_type_create_from_typespec_checked that has proper error handling
Syntax
MonoType* mono_type_create_from_typespec (MonoImage *image, guint32 type_spec)

Parameters
image context where the image is created
type_spec typespec token
Description

Creates a MonoType representing the TypeSpec indexed by the type_spec token.

mono_type_full_name
Syntax
char* mono_type_full_name (MonoType *type)

mono_type_get_array_type
Syntax
MonoArrayType* mono_type_get_array_type (MonoType *type)

Parameters
type the MonoType operated on
Return value
a MonoArrayType struct describing the array type that type represents. The info includes details such as rank, array element type and the sizes and bounds of multidimensional arrays.
Description
It is only valid to call this function if type is a MONO_TYPE_ARRAY .
mono_type_get_class
Syntax
MonoClass* mono_type_get_class (MonoType *type)

Parameters
type the MonoType operated on
Return value
the MonoClass pointer that describes the class that type represents.
Description
It is only valid to call this function if type is a MONO_TYPE_CLASS or a MONO_TYPE_VALUETYPE . For more general functionality, use mono_class_from_mono_type_internal, instead.
mono_type_get_modifiers

Syntax
char* mono_type_get_name (MonoType *type)

Parameters
type a type
Return value
The string representation for type as it would be represented in IL code.
mono_type_get_ptr_type
Syntax
MonoType* mono_type_get_ptr_type (MonoType *type)

Return value
the MonoType pointer that describes the type that type represents a pointer to.
Description
\pararm type the MonoType operated on It is only valid to call this function if type is a MONO_TYPE_PTR .
mono_type_get_signature
Syntax
MonoMethodSignature* mono_type_get_signature (MonoType *type)

Parameters
type the MonoType operated on
Return value
the MonoMethodSignature pointer that describes the signature of the function pointer type represents.
Description
It is only valid to call this function if type is a MONO_TYPE_FNPTR .
mono_type_get_type
Syntax
int mono_type_get_type (MonoType *type)

Parameters
type the MonoType operated on
Return value
the IL type value for type. This is one of the MonoTypeEnum enum members like MONO_TYPE_I4 or MONO_TYPE_STRING.
mono_type_get_underlying_type
Syntax
MonoType* mono_type_get_underlying_type (MonoType *type)

Parameters
type a type
Return value
The MonoType for the underlying integer type if type is an enum and byref is false, otherwise the type itself.
mono_type_is_byref
Syntax
mono_bool mono_type_is_byref (MonoType *type)

Parameters
type the MonoType operated on
Return value
TRUE if type represents a type passed by reference, FALSE otherwise.
mono_type_is_pointer
Syntax
mono_bool mono_type_is_pointer (MonoType *type)

Parameters
type the MonoType operated on
Return value
TRUE if type is a managed or unmanaged pointer type. FALSE otherwise.
mono_type_is_reference
Syntax
mono_bool mono_type_is_reference (MonoType *type)

Parameters
type the MonoType operated on
Return value
TRUE if type represents an object reference. FALSE otherwise.
mono_type_is_struct
Syntax
mono_bool mono_type_is_struct (MonoType *type)

Parameters
type the MonoType operated on
Return value
TRUE if type is a struct, that is a ValueType but not an enum or a basic type like System.Int32 . FALSE otherwise.
mono_type_is_void
Syntax
mono_bool mono_type_is_void (MonoType *type)

Parameters
type the MonoType operated on
Return value
TRUE if type is System.Void . FALSE otherwise.
mono_type_size
Syntax
int mono_type_size (MonoType *t, int *align)

Parameters
t the type to return the size of
Return value
The number of bytes required to hold an instance of this type in memory
mono_type_stack_size
Syntax
int mono_type_stack_size (MonoType *t, int *align)

Parameters
t the type to return the size it uses on the stack
Return value
The number of bytes required to hold an instance of this type on the runtime stack
mono_type_to_unmanaged
Syntax
guint32 // FIXMEcxx MonoMarshalNative mono_type_to_unmanaged (MonoType *type, MonoMarshalSpec *mspec, gboolean as_field, gboolean unicode, MonoMarshalConv *conv)

Return value
A MonoMarshalNative enumeration value (MONO_NATIVE_) value describing the underlying native reprensetation of the type.
Description
The value pointed to by conv will contain the kind of marshalling required for this particular type one of the MONO_MARSHAL_CONV_ enumeration values.
