C# 通过遍历设置控件属性

 foreach (Control control in this.Controls)
            {
                if (control is Button)
                {
                    if(control.Name == "button1")
                    control.Enabled = false;
                }
            }

Label[] lb = new Label[3] { label1, label2, label3 };
            for (int i = 0; i < 3; i++)
            {
                lb[i].Text = "label*" + i.ToString();
            }
