Question

I have an object model that has a property like this:

public class SomeModel
{
   public string SomeString { get; set; }

   public void DoSomeWork()
   {
      ....
   }
}

I want the DoSomeWork function to execute automatically after the SomeString property changes. I tried this but it’s not working:

public string SomeString { get; set { DoSomeWork(); } }

What’s the correct syntax?

Answer 1

Use a private field instead, like this …

public class SomeModel
{
    private string someString = "";

    public string SomeString {
        get { return this.someString; }
        set {
            this.someString = value;
            this.DoSomeWork();
        }
    }

   public void DoSomeWork()
   {
      ....
   }
}
