PropertyType Property

PropertyInfo.PropertyType Property


Gets the type of this property.

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

public abstract Type PropertyType { get; }

Property Value

Type: System.Type

The type of this property.

To determine the type of a particular property, do the following:

  1. Get a Type object that represents the type (the class or structure) that contains the property. If you are working with an object (an instance of a type), you can call its GetType method. Otherwise, you can use the C# operator or the Visual Basic operator, as the example illustrates.

  2. Get a PropertyInfo object that represents the property in which you're interested. You can do this by getting an array of all properties from the Type.GetProperties method and then iterating the elements in the array, or you can retrieve the PropertyInfo object that represents the property directly by calling the Type.GetProperty method and specifying the property name.

  3. Retrieve the value of the PropertyType property from the PropertyInfo object.

The following example defines an Employee class that has five properties. It then uses retrieves an array of PropertyInfo objects that represent those properties and displays the name and type of each.

using System;
using System.Reflection;

public class Employee
   private string _id;

   public String FirstName { get; set; }
   public String MiddleName { get; set; }
   public String LastName  { get; set; }
   public DateTime HireDate  { get; set; }

   public String ID
      get { return _id; }
      set {
         if (ID.Trim().Length != 9)
            throw new ArgumentException("The ID is invalid");
         _id = value;

public class Example
   public static void Main()
      Type t = typeof(Employee);
      Console.WriteLine("The {0} type has the following properties: ",
      foreach (var prop in t.GetProperties())
         Console.WriteLine("   {0} ({1})", prop.Name,
// The example displays the following output:
//       The Employee type has the following properties:
//          FirstName (String)
//          MiddleName (String)
//          LastName (String)
//          HireDate (DateTime)
//          ID (String)
