Assembly: System.Core (in System.Core.dll)
Type Parameters
- TResult
The type of the value to be repeated in the result sequence.
Parameters
- element
- Type: TResult
The value to be repeated.
- count
- Type: System.Int32
The number of times to repeat the value in the generated sequence.
Return Value
Type: System.Collections.Generic.IEnumerable<TResult>An IEnumerable<T> that contains a repeated value.

This method is implemented by using deferred execution. The immediate return value is an object that stores all the information that is required to perform the action. The query represented by this method is not executed until the object is enumerated either by calling its GetEnumerator method directly or by using foreach in Visual C# or For Each in Visual Basic.
The following code example demonstrates how to use Repeat<TResult> to generate a sequence of a repeated value.
IEnumerable<string> strings =
Enumerable.Repeat("I like programming.", 15);
foreach (String str in strings)
{
Console.WriteLine(str);
}
/*
