[导入]将多个复选框的值赋值给一个字符串或一个数组

后台主要代码：
protected void CheckBox_CheckedChanged(object sender, EventArgs e)
    {
        string checkResult = "";
         ResultLabel.Text = "";
                
         if (A.Checked)
         {
             checkResult += A.ID + ",";
         }
         if (B.Checked)
         {
             checkResult += B.ID + ",";
         }
         if (C.Checked)
         {
             checkResult += C.ID;
         }
         ResultLabel.Text = checkResult.Trim();
    }

 protected void x_CheckedChanged(object sender, EventArgs e)
    {
        int[] strResult = new int[3];
        string str = "";
        xLabel.Text = "";
        for (int i = 0; i <strResult.Length; i++)
        {
            strResult[i] = 0;
        }
        //*        strResult[0] = 0;        strResult[1] = 0;        strResult[2] = 0;
      
        if (x.Checked)
        {
            strResult[0] = 1;           
           
        }
        if (y.Checked)
        {
            strResult[1] = 1;          
           
        }
        if (z.Checked)
        {
            strResult[2] = 1;                 
        }
     
        for (int i = 0; i < strResult.Length; i++)
        {
            str += strResult[i].ToString();
        }
          xLabel.Text = str;

    }
