Using linq over datatable

This sample uses Except to create a sequence that contains the values from numbersAthat are not also in numbersB.

public void DataSetLinq52() {

var numbersA = testDS.Tables["NumbersA"].AsEnumerable();
var numbersB = testDS.Tables["NumbersB"].AsEnumerable();

var aOnlyNumbers = numbersA.Except(numbersB, DataRowComparer.Default);

Console.WriteLine("Numbers in first array but not second array:");
foreach (var n in aOnlyNumbers) {
Console.WriteLine(n["number"]);
}
}

Best Regard's
Tiju Thankachan
