动态创建多个文本框C#

Question

这是我的代码.但是我的所有文本框的值都是空的.

    public void createTxtTeamNames()
    {
        TextBox[] txtTeamNames = new TextBox[teams];
        int i = 0;
        foreach (TextBox txt in txtTeamNames)
        {
            string name = "TeamNumber" + i.ToString();
            txt.Name = name;
            txt.Text = name;
            txt.Location = new Point(172, 32 + (i * 28));
            txt.Visible = true;
            i++;
        }
    }

谢谢您的帮助.

数组创建调用只是将元素初始化为null.您需要单独创建它们.

TextBox[] txtTeamNames = new TextBox[teams];
for (int i = 0; i < txtTeamNames.Length; i++) {
  var txt = new TextBox();
  txtTeamNames[i] = txt;
  txt.Name = name;
  txt.Text = name;
  txt.Location = new Point(172, 32 + (i * 28));
  txt.Visible = true;
}

注意:正如有几个人指出的那样,为了使这个代码有意义,你需要将每个代码添加TextBox到父代码中Control
