如何查找单击哪组文本框

Question

我有两个Textbox []

_textBox1 = new TextBox[] {textBox1,textBox2...};
_textBox2 = new TextBox[] {textBox10,textBox11....};

第一个有11个元素，第二个有6个元素。

但两者都使用相同的光标向上/向下程序（使用标签）

对象发件人是否可以使用哪个文本框组？

在下面的程序中我如何使用_textBox1和_textBox2

    private void KeyMove_Click(object sender, MouseEventArgs e)
    {
        var textBox = sender as TextBox;                 //from there
        if (textBox != null)                 
        {
            if (textBox.AccessibleName == "first")
            {
                Yer = 0;
            }
            else if (textBox.AccessibleName ==null)
            {
                Yer = 1;
            }
        }                                                // till here with idea of MarcinJuraszek
        try
        {
            string id = (sender as Control).Tag.ToString();
            KeyIndex = Convert.ToInt32(id);
        }
        catch (Exception e1)
        {
            MessageBox.Show(e1.Message.ToString());
        }
        if (grp == 0)                         // I am using 1st group of textbox

Answer 1

您可以尝试将sender投射到TextBox

var textBox = sender as TextBox;

然后检查哪个组包含该实例：

if(textBox != null)
{
    if(_textBox1.Contains(textBox))
    {
        // first group
    }
    else if(_textBox2.Contains(textBox))
    {
        // second group
    }
    else
    {
        // some other textbox?
    }
}
else
{
    // sender is not a TextBox instance
}

您需要在文件顶部using System.Linq;拨打Contains电话。
