asp.net下实现输入数字的冒泡排序

protected void btnSort_Click(object sender, EventArgs e) 
{ 
string array1 = txtSort.Text.Trim(); 
string[] array21=array1.Split(','); 
int dxiao = array21.Length; 
int[] array = new int[dxiao]; 
int temp=0; 
for (int i = 0; i < array.Length; i++) 
{ 
array[i] = Convert.ToInt32(array21[i]); 
} 
for (int i = 0; i < array.Length - 1; i++) 
{ 
for (int j = i + 1; j < array.Length; j++) 
{ 
if (array[j] < array[i]) 
{ 
temp = array[i]; 
array[i] = array[j]; 
array[j] = temp; 
} 
} 
} 
for (int i = 0; i < dxiao; i++) 
{ 
lbsort.Text = lbsort.Text + " " + Convert.ToString(array[i]); 
} 
}
