我现在是通过每个控件的KeyPress事件来取得回车事件切换到下一控件,
这样就要在每个控件上都要写,每个控件都要写,
  private void txtCardid_KeyPress(object sender, KeyPressEventArgs e)
        {
            if (e.KeyChar == (char)13)
            {
                this.cobIsjiankong.Focus();
            }
        }
上面就是在txtCardid控件的KeyPress事件上选择coblsjiankong控件,
请问如何让回车键通过简单方法来实现这一功能?
控件的Tabindex值现在是从0按顺序排列的
具体我不知怎么写，请大家帮忙！谢谢！！！

将所有的控件keypress事件注册到同一个_keypress()中，之后在里面用foreach看看

public partial class Form1 : Form
    {
        private int i= 0;
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            this.textBox1.Focus();
            
            //keyindex = this.textBox1.TabIndex;
        }

        private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
        {
            if (e.KeyChar == (char)13)
            {
                i++;
                if (i > 3)
                    i = 0;
                foreach (System.Windows.Forms.Control c in this.Controls)
                {
                    if (c is TextBox)
                    {
                        if (c.TabIndex == i)
                            c.Focus();
                    }
                }
            }
        }

        
    }
窗体上有四个文本框,他们的TabIndex是从0到3顺序排列,每个文本框的KeyPress事件都是这个事件,即可实现

如果窗体上不光是文本框还有其他控件可以这样写：（注意：好像Button不能实现）
public partial class Form1 : Form
    {
        private int i= 0;
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            this.textBox1.Focus();
            
            //keyindex = this.textBox1.TabIndex;
        }

        private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
        {
            if (e.KeyChar == (char)13)
            {
                i++;
                if (i > 4)
                    i = 0;
                foreach (System.Windows.Forms.Control c in this.Controls)
                {
                    //if (c is TextBox)
                    //{
                        if (c.TabIndex == i)
                            c.Focus();
                    //}
                }
            }
        }

        
    }
