How to get a property value based on the name

Question

is there a way to get the value of a property of a object based on its name   For example if I have   public class Car   Vehicle      public string Make   get  set        and  var car   new Car   Make  Ford       I want to write a method where I can pass in the property name and it would return the property value  ie   public string GetPropertyValue string propertyName       return the value of the property

Expanding on Adam Rackis s answer - we can make the extension method generic simply like this   public static TResult GetPropertyValue lt TResult gt  this object t  string propertyName        object val   t GetType   GetProperties   Single pi   gt  pi Name    propertyName  GetValue t  null       return  TResult val      You can throw some error handling around that too if you like

To avoid reflection you could set up a Dictionary with your propery names as keys and functions in the dictionary value part that return the corresponding values from the properties that you request

You d have to use reflection  public object GetPropertyValue object car  string propertyName       return car GetType   GetProperties          Single pi   gt  pi Name    propertyName         GetValue car  null       If you want to be really fancy  you could make it an extension method   public static object GetPropertyValue this object car  string propertyName       return car GetType   GetProperties          Single pi   gt  pi Name    propertyName         GetValue car  null       And then   string makeValue    string car GetPropertyValue  Make
