Answer 1

使用TextBox.Text =“bla”而不是强制转换

Answer 2

假设您使用Form的方法调用代码，您需要类似的内容：

  String data = "test";

  // creation of a new TextBox with Text assigned to data... 
  TextBox tb = new TextBox() {
    Parent = this, // <- text box is on the Form...
    Location = new Point(10, 10),
    Size = new Size(100, 20),
    Text = data, // <- TEXT of the TextBox is data
    BackColor = Color.Black,
    ForeColor = Color.White,
  };

Answer 3

String data = "test";
TextBox tb = new TextBox();
tb.text = data;

您可以使用text属性将字符串直接分配给文本框。希望这会有所帮助。
