Type.GetPropertyImpl Method

When overridden in a derived class, searches for the specified property whose parameters match the specified argument types and modifiers, using the specified binding constraints.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

protected abstract PropertyInfo GetPropertyImpl(
	string name,
	BindingFlags bindingAttr,
	Binder binder,
	Type returnType,
	Type[] types,
	ParameterModifier[] modifiers
)

Parameters

name
Type: System.String
The string containing the name of the property to get.
bindingAttr
Type: System.Reflection.BindingFlags
A bitmask comprised of one or more BindingFlags that specify how the search is conducted.
-or-
Zero, to return null.
binder
Type: System.Reflection.Binder
An object that defines a set of properties and enables binding, which can involve selection of an overloaded member, coercion of argument types, and invocation of a member through reflection.
-or-
A null reference (Nothing in Visual Basic), to use the DefaultBinder.
returnType
Type: System.Type
The return type of the property.
types
Type: System.Type[]
An array of Type objects representing the number, order, and type of the parameters for the indexed property to get.
-or-
An empty array of the type Type (that is, Type[] types = new Type[0]) to get a property that is not indexed.
modifiers
Type: System.Reflection.ParameterModifier[]
An array of ParameterModifier objects representing the attributes associated with the corresponding element in the types array. The default binder does not process this parameter.

Return Value

Type: System.Reflection.PropertyInfo
An object representing the property that matches the specified requirements, if found; otherwise, null.

ExceptionCondition
AmbiguousMatchException

More than one property is found with the specified name and matching the specified binding constraints.

ArgumentNullException

name is null.

-or-

types is null.

-or-

One of the elements in types is null.

ArgumentException

types is multidimensional.

-or-

modifiers is multidimensional.

-or-

types and modifiers do not have the same length.

NotSupportedException

The current type is a TypeBuilder, EnumBuilder, or GenericTypeParameterBuilder.

Although the default binder does not process ParameterModifier (the modifiers parameter), you can use the abstract System.Reflection.Binder class to write a custom binder that does process modifiers. ParameterModifier is only used when calling through COM interop, and only parameters that are passed by reference are handled.

The following BindingFlags filter flags can be used to define which properties to include in the search:

  • You must specify either BindingFlags.Instance or BindingFlags.Static in order to get a return.

  • Specify BindingFlags.Public to include public properties in the search.

  • Specify BindingFlags.NonPublic to include non-public properties (that is, private, internal, and protected properties) in the search.

  • Specify BindingFlags.FlattenHierarchy to include public and protected static members up the hierarchy; private static members in inherited classes are not included.

The following BindingFlags modifier flags can be used to change how the search works:

  • BindingFlags.IgnoreCase to ignore the case of name.

  • BindingFlags.DeclaredOnly to search only the properties declared on the Type, not properties that were simply inherited.

See System.Reflection.BindingFlags for more information.
