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; }

技术分享

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();
