Searches for the specified public property whose parameters match the specified argument types and modifiers.
- name
- The string containing the name of the public property to get.
- returnType
- The return type of the property.
- types
- An array of Type objects representing the number, order, and type of the parameters for the indexed property to get.
- modifiers
- An array of System.Reflection.ParameterModifier objects representing the attributes associated with the corresponding element in the types array. The default binder does not process this parameter.
An object representing the public property that matches the specified requirements, if found; otherwise, null.
A property is considered public to reflection if it has at least one accessor that is public. Otherwise the property is considered private, and you must use System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.Static (in Visual Basic, combine the values using Or) to get it.
Although the default binder does not process System.Reflection.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 search for name is case-sensitive. The search includes public static and public instance properties.
If the current Type represents a constructed generic type, this method returns the System.Reflection.PropertyInfo with the type parameters replaced by the appropriate type arguments.
If the current Type represents a type parameter in the definition of a generic type or generic method, this method searches the properties of the class constraint.
vbprvblong, csprcslong, and vcprvclong have simplified syntax for accessing indexed properties and allow one indexed property to be a default for its type. For example, if the variable myList refers to an ArrayList, the syntax myList[3] (myList(3) in Visual Basic) retrieves the element with the index of 3. You can overload the property.
In C#, this feature is called an indexer and cannot be refered to by name. By default, a C# indexer appears in metadata as an indexed property named "Item". However, a class library developer can use the System.Runtime.CompilerServices.IndexerNameAttribute attribute to change the name of the indexer in the metadata. For example, the string class has an indexer named string.Chars(int). Indexed properties created using languages other than C# can have names other than Item, as well.
To determine whether a type has a default property, use the System.Reflection.MemberInfo.GetCustomAttributes(Type, bool) method to test for the System.Reflection.DefaultMemberAttribute attribute. If the type has System.Reflection.DefaultMemberAttribute, the System.Reflection.DefaultMemberAttribute.MemberName property returns the name of the default property.
