[ASP.net教程]c# WinForm 文本输入对话框


这种功能为什么不向MessageBox一样自带,还得自己写~~


 

代码:

public InputBox(string label){  InitializeComponent();  label1.Text = label;}public InputBox(string label, string title){  InitializeComponent();  label1.Text = label;  this.Text = title;}//取消private void button2_Click(object sender, EventArgs e){  this.DialogResult = DialogResult.Cancel;  this.Close();}//确定private void button1_Click(object sender, EventArgs e){  this.DialogResult = DialogResult.OK;  Value = textBox1.Text;  this.Close();}private void InputBox_Load(object sender, EventArgs e){  textBox1.Focus();  textBox1.Text = Value;}public string Value { get; set; }

窗体设计:

注意修改窗口属性:

this.AcceptButton = this.button1;this.CancelButton = this.button2;this.FormBorderStyle = FormBorderStyle.FixedDialog;


用法:

InputBox inp = new InputBox("Lable内的值");DialogResult dr = inp.ShowDialog();if (dr == DialogResult.OK && inp.Value.Length > 0){  操作代码}inp.Dispose();
