Wrap them in an object:
public RelayCommand<MyModel> MyCommand { get; set; }
where MyModel will contain the two properties:
public class MyModel
{
public int Id { get; set; }
public string Name { get; set; }
}

@mtaboy, the way RelayCommand is defined, there is only one type you can pass. So if you want multiple types you will have to wrap them into a separate model as shown in my answer. – Darin Dimitrov Nov 26 '11 at 16:28

How can you set Id And Name in xaml code as MyModel ? – M.Azad Nov 26 '11 at 16:36

@mtaboy, your main view model could have a property of this type. Then you could use the CommandParameter with the correct binding syntax. – Darin Dimitrov Nov 26 '11 at 16:38

You can use a distinct model class in order to pass several parameters. And in order to initialize them, you can use xaml elements like this:
<Button Command="{Binding YourCommand}">
<Button.CommandParameter>
<YourNS:YourModel Id="{Binding PathForId}" Name="{Binding PathForName}"/>
</Button.CommandParameter>
</Button>
This will construct a new YourModel object to pass to a command, and then will initialize its properties via bindings.

1Actually this didn't end up working out for me in Silverlight. Instead I used the custom multibinding class mentioned in this article: http://www.codeproject.com/Articles/286171/MultiBinding-in-Silverlight-5 - no converter is needed, you just need to cast the object in to an object[]. – Doguhan Uluca Apr 10 '12 at 18:10
