如何控制几个控件他们共同的一个属性

Question

有事件的吗?如果有可以搞定
 ((Object)sender).Visble=false;

Answer 1

原理：用hasttable来存储他们的引用; 
int[] i = new int[] { 0, 1, 1, 1,1 };
            hashtable = new Hashtable();
            int k=0;
            foreach (Control con in Controls)
            {
                k++;
                object obj = (object)con;
                hashtable.Add(k.ToString(),obj);
            }
            for (int j = 0; j < i.Length; j++)
            {
               object obj = hashtable[j.ToString ()];             
                if (i[j] == 1)
                {
                    try
                    {
                        if (obj is Button)
                        {
                            Button btn = (Button)obj;
                            btn.Visible = false;
                        }
                        if (obj is TextBox)
                        {
                            TextBox tb = (TextBox)obj;
                            tb.Visible = false;
                        }//有别的控件时，可以添加
                    }
                    catch(Exception er)
                    {
                        MessageBox.Show(er.Message );
                    }
                }
                
            }
        }
