Answer 2

if you want it to be generic, youll have to use reflection to loop through the members and build the query xml dynamically. something like:

Type type = TypeOf(Contact);
PropertyInfo[] properties = type.GetProperties();

foreach (PropertyInfo property in properties)
{
    /////here you chain the members for the xml
    Console.WriteLine("Name: " + property.Name + ", Value: " + property.GetValue(obj, null));
}

Retrieving “all attributes” is computationally more expensive than retrieving just those you need (also consider the IO cost). If you are looking for a way to view the attributes then write code for just those you need try this:

In the CRM web GUI:

1.Navigate to the view that displays the records in question 2.Click the Advanced Find button in the Ribbon Bar 3.Configure your “find” until it shows the records you are looking for 4.Click the Download Fetch XML button in the Ribbon Bar 5.Open the file with a text viewer (or your favorite development tool)

If you want to use this XML directly you might consider:
