用c# 产生一个 int 数组 长度为100,并向其中随机插入 1-100 ,并且不能重复

class getRandowArray
{
public getRandowArray()
{
arr = new int[100];
}
int[] arr;

/// <summary>
/// 检查数组中是否已存在此数
/// </summary>
/// <returns>ture为已存在</returns>
private bool checkNumber(int arrlist)
{
for (int i = 0; i < arrlist; ++i)
{
if (arr[i] == arr[arrlist])
return true;
}
return false;
}

/// <summary>
/// 生成数组
/// </summary>
/// <returns>数组</returns>
public int[] produceRandomArray()
{
Random rd=new Random();
for (int i = 0; i < 100; ++i)
{
//int temp=0;

do
{
//temp = rd.Next(1, 101);
//arr[i] = temp;
arr[i] = rd.Next(1, 101);
}
while (checkNumber(i));
}
return arr;
}
}
