Name
ParameterInfo
Synopsis
This class allows the inspection
of the type and behavior of a method
parameter. Because parameters can have custom attributes on them, the
class implements ICustomAttributeProvider
.
Attributes
returns the attributes defined on this
parameter. If the parameter has a default, it is stored in
DefaultValue
. Retrieve the name, type, and member
the parameter is from by inspecting Name
,
ParameterType
, and Member
.
Position
returns the ordinal position of this
parameter. IsOptional
returns
true
if the parameter is optional, and
IsLcid
indicates when the parameter is a locale
identifier.
A parameter is passed by reference if the IsByRef
property of its ParameterType
property is
true
and the IsOut
property is
false
(out parameters have
IsByRef
and IsOut
set to
true
). A parameter that has been marked as
[In]
has IsOut
set to
false
and IsIn
set to
true
.
