请用C#语言编写一个类，实现对数组 int[] {1,5,13,6,10,55,99,2,87,12,34,75,33,47}的排序；

public string ReturnSort(int[] iArray)
{
ArrayList al = new ArrayList();
StringBuilder sbr = new StringBuilder();
for (int i = 0; i < kk.Length; i++)
{
al.Add(kk[i]);
}
al.Sort();
for (int i = 0; i < al.Count; i++)
{
sbr.Append(al[i].ToString() + "|");
}
return sbr.ToString();
}
public int[] ReturnBySort(int[] iArray)
{
ArrayList al = new ArrayList();
int[] iTemp = new int[iArray.Length];
for (int i = 0; i < iArray.Length; i++)
{
al.Add(iArray[i]);
}
al.Sort();
for (int i = 0; i < al.Count; i++)
{
iTemp[i] = Convert.ToInt32(al[i]);
}
return iTemp;
}

楼上的.好恶心呢..
拿数组排序,.,.太强了，强!
