Type.GetProperty Method (String, Type)
Searches for the specified public property whose parameters match the specified argument types.
Assembly: mscorlib (in mscorlib.dll)
abstract GetProperty : name:string * types:Type -> PropertyInfo override GetProperty : name:string * types:Type -> PropertyInfo
- Type: System.String
The string containing the name of the public property to get.
Return ValueType: System.Reflection.PropertyInfo
An object representing the public property whose parameters match the specified argument types, if found; otherwise, a null reference (Nothing in Visual Basic).
More than one property is found with the specified name and matching the specified argument types.
name is a null reference (Nothing in Visual Basic).
types is a null reference (Nothing in Visual Basic).
types is multidimensional.
An element of types is a null reference (Nothing in Visual Basic).
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 BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.Static (in Visual Basic, combine the values using Or) to get it.
The search for name is case-sensitive. The search includes public static and public instance properties.
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.
Indexers and Default Properties
Visual Basic 2005, Visual C# 2005, and Visual C++ 2005 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 (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 IndexerNameAttribute attribute to change the name of the indexer in the metadata. For example, the String class has an indexer named Chars. 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 GetCustomAttributes(Type, Boolean) method to test for the DefaultMemberAttribute attribute. If the type has DefaultMemberAttribute, the MemberName property returns the name of the default property.
The following example retrieves the Type object of a user-defined class, retrieves the property of that class, and displays the property name and type of the property as specified by the arguments passed to GetProperty.
