本文展示了如何使用C#中的Enumerable.Range和Enumerable.Repeat方法来生成指定范围内的整数序列和重复字符串序列，并通过示例代码进行演示。
static void Main()
{
UseRangeMethod();
UseRepeatMethod();
}
public static void UseRangeMethod()
{
var rangeNumber =
from element in Enumerable.Range(1, 10)
select new { n = element, oddEven = element % 2 == 1 ? "Odd" : "Even" };
Console.WriteLine("Use range to generate a sequence of numbers from 1 to 10 that is used to find which numbers in the range are odd and even");
foreach (var number in rangeNumber)
{
Console.WriteLine("number:{0} is {1}",number.n,number.oddEven);
}
}
public static void UseRepeatMethod()
{
var repeatNumber = Enumerable.Repeat("Guo", 5);
Console.WriteLine("Use repeat to generate a sequence that contains Guo five times");
foreach (var number in repeatNumber)
{
Console.WriteLine("{0}", number);
}
}
