# Enumerable.Range(Int32, Int32)Enumerable.Range(Int32, Int32)Enumerable.Range(Int32, Int32)Enumerable.Range(Int32, Int32) Method

## 定義

``````public:
static System::Collections::Generic::IEnumerable<int> ^ Range(int start, int count);``````
``public static System.Collections.Generic.IEnumerable<int> Range (int start, int count);``
``static member Range : int * int -> seq<int>``
``Public Function Range (start As Integer, count As Integer) As IEnumerable(Of Integer)``

#### 參數

start
Int32 Int32 Int32 Int32

count
Int32 Int32 Int32 Int32

#### 例外狀況

`count` 小於 0。`count` is less than 0.

-或--or- `start` + `count` -1 大於 MaxValue`start` + `count` -1 is larger than MaxValue.

## 範例

``````// Generate a sequence of integers from 1 to 10
// and then select their squares.
IEnumerable<int> squares = Enumerable.Range(1, 10).Select(x => x * x);

foreach (int num in squares)
{
Console.WriteLine(num);
}

/*
This code produces the following output:
