  • 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();
