[c#] "Use the new keyword if hiding was intended" warning

I have a warning at the bottom of my screen:

Warning 1 'WindowsFormsApplication2.EventControlDataSet.Events' hides inherited member 'System.ComponentModel.MarshalByValueComponent.Events'. Use the new keyword if hiding was intended. C:\Users\myComputer\Desktop\Event Control\WindowsFormsApplication2\EventControlDataSet.Designer.cs 112 32 eventControl

If i double click on it, it comes up with:

public EventsDataTable Events {
    get {
        return this.tableEvents;
    }

Can anyone tell me how to get rid of this?

@wdavo is correct. The same is also true for functions.

If you override a base function, like Update, then in your subclass you need:

new void Update()
{
  //do stufff
}

Without the new at the start of the function decleration you will get the warning flag.

In the code below, Class A implements the interface IShow and implements its method ShowData. Class B inherits Class A. In order to use ShowData method in Class B, we have to use keyword new in the ShowData method in order to hide the base class Class A method and use override keyword in order to extend the method.

interface IShow
{
    protected void ShowData();
}

class A : IShow
{
    protected void ShowData()
    {
        Console.WriteLine("This is Class A");
    }
}

class B : A
{
    protected new void ShowData()
    {
        Console.WriteLine("This is Class B");
    }
}

The parent function needs the virtual keyword, and the child function needs the override keyword in front of the function definition.
