Type.GetProperty Method (String, Type)

Searches for the public property with the specified name and return type.

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

public PropertyInfo GetProperty(
	string name,
	Type returnType


Type: System.String
The String containing the name of the public property to get.
Type: System.Type
The return type of the property.

Return Value

Type: System.Reflection.PropertyInfo
A PropertyInfo object representing the public property with the specified name, if found; otherwise, null.


More than one property is found with the specified name.


name is null, or returnType is 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 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 constructed generic type, this method returns the 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.

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 a List<T>, 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 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 defines a class with one property and retrieves the name and type of the property.

using System;
using System.Reflection;

class MyClass1
   String myMessage = "Hello World.";
   public string MyProperty1
         return myMessage;
         myMessage = value;
class Example
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
         Type myType = typeof(MyClass1);
         // Get the PropertyInfo object representing MyProperty1. 
         PropertyInfo myStringProperties1 = myType.GetProperty("MyProperty1",
         outputBlock.Text += String.Format("The name of the first property of MyClass1 is {0}.", myStringProperties1.Name) + "\n";
         outputBlock.Text += String.Format("The type of the first property of MyClass1 is {0}.", myStringProperties1.PropertyType) + "\n";
      catch (ArgumentNullException e)
         outputBlock.Text += "ArgumentNullException :" + e.Message + "\n";

      catch (AmbiguousMatchException e)
         outputBlock.Text += "AmbiguousMatchException :" + e.Message + "\n";
      catch (NullReferenceException e)
         outputBlock.Text += String.Format("Message : {0}", e.Message) + "\n";
      //The name of the first property of MyClass1 is MyProperty1.
      //The type of the first property of MyClass1 is System.String.
