我的部分代码：  private void button1_Click(object sender, EventArgs e)
        {
            string x=textBox1.Text;
            int c=Convert.ToInt32(x);
            string y=textBox2.Text;
            int a=Convert.ToInt32(y);
            string z=textBox3.Text;
            int b=Convert.ToInt32(z);          //以上从界面获取数据并转为整形

            int[] num=new int[c];
            
            Random r=new Random();
            for (int i=0;i<=c-1;i++)
            {
                num[i] = r.Next(a, b);
                listBox1.Items.Add(num[i]);    //以上获取随机数并将数据显示于listbox               
                int[] num1 = Array.Sort(num);
                checkedListBox1.Items.AddRange(num1);
               
               
             }
结果显示 无法将类型“void”隐式转换为“int[]”.......求解释
 

int[] num1 = Array.Sort(num);
改成Array.Sort(num);就OK了

Array.Sort(num)只是将num排序;
int[] num1=num;
num1同样也不能显示转换为item[],
checkedListBox1.Items.AddRange(num1);也不行;

知道了， thanks！
