Repeat
The Repeat operator creates a single value sequence that repeats itself a specified number of
times. The following example creates a sequence of a single string value and repeats that string
10 times:
var coolphrase = Enumerable.Repeat("LINQ ROCKS!", 10);
for each (string phrase in coolphrase)
listbox1.Items.Add(phrase);
The result of this query is the phrase ??????LINQ ROCKS!??™??™ output 10 times to the list box.
Conversion Operators
Conversion refers to the act of changing the type of input objects to the sequence. The conversion
operators do just this, and they are discussed in this section.

AsEnumerable
The AsEnumerable operator returns the query input typed as IEnumerable(Of T), meaning that you can
change the data source from a type that implements IEnumerable(Of T) to IEnumerable(Of T) itself.
The following example uses the AsEnumerable operator to replace the type??™s custom Where method with
that of the standard query operator Where.
