Enumerable.Repeat(TResult, Int32)
Enumerable.Repeat(TResult, Int32)
Method
Definition
Generates a sequence that contains one repeated value.
public:
generic <typename TResult>
static System::Collections::Generic::IEnumerable<TResult> ^ Repeat(TResult element, int count);
public static System.Collections.Generic.IEnumerable<TResult> Repeat<TResult> (TResult element, int count);
Public Function Repeat(Of TResult) (element As TResult, count As Integer) As IEnumerable(Of TResult)
Type Parameters
- TResult
The type of the value to be repeated in the result sequence.
Parameters
- element
The value to be repeated.
Returns
IEnumerable<TResult>
An IEnumerable<T> that contains a repeated value.
Exceptions
count
is less than 0.
Examples
The following code example demonstrates how to use Repeat 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);
}
/*

' Repeat the same string to create a sequence.
Dim sentences As IEnumerable(Of String) =
Enumerable.Repeat("I like programming.", 15)
Dim output As New System.Text.StringBuilder
For Each sentence As String In sentences
output.AppendLine(sentence)
Next
' Display the output.
MsgBox(output.ToString())
' This code produces the following output:
'

Remarks
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.
