Question

我有windows-mobile程序，有两种形式。

在form1中，我有TextBox，在form2中，我有5个按钮。

当我按下form2中的按钮我会在form1的文本框中看到它们时如何做到这一点

Answer 1

在表单上创建一个公共属性，允许调用表单访问所选值。

public partial class SelectionForm : Form
{
    public SelectionForm()
    {
        InitializeComponent();
    }

    //Selection holder
    private string _selection;

    //Public access to this item
    public string Selection { get { return _selection; } }

    private void button1_Click(object sender, EventArgs e)
    {
        _selection = "One was selected";
        this.Close();
    }

    private void button2_Click(object sender, EventArgs e)
    {
        _selection = "Two was selected";
        this.Close();
    }
}

然后，从您的调用表单中，您可以在表单处理之前获取此值。

public partial class TextForm : Form
{
    public TextForm()
    {
        InitializeComponent();
    }

    private void btnSelect_Click(object sender, EventArgs e)
    {
        using (SelectionForm selectionForm = new SelectionForm())
        {
            selectionForm.ShowDialog();
            txtSelection.Text = selectionForm.Selection;
        }
    }
}
