是否有一种标准方法可以从Windows窗体中的自定义对话框返回值？

public enum DialogResult
{
    Ok,
    Cancel,
    Yes,
    No
}

public partial class CustomDialog : Form
{
    public DialogResult Result { get; private set; }

    // 其他代码...
}

private void btnOk_Click(object sender, EventArgs e)
{
    Result = DialogResult.Ok;
    this.Close();
}

private void btnCancel_Click(object sender, EventArgs e)
{
    Result = DialogResult.Cancel;
    this.Close();
}

private void btnYes_Click(object sender, EventArgs e)
{
    Result = DialogResult.Yes;
    this.Close();
}

private void btnNo_Click(object sender, EventArgs e)
{
    Result = DialogResult.No;
    this.Close();
}

private void btnShowDialog_Click(object sender, EventArgs e)
{
    var dialog = new CustomDialog();
    dialog.ShowDialog();

    if (dialog.Result == DialogResult.Ok)
    {
        // 处理“确定”按钮的单击事件
    }
    else if (dialog.Result == DialogResult.Cancel)
    {
        // 处理“取消”按钮的单击事件
    }
    else if (dialog.Result == DialogResult.Yes)
    {
        // 处理“是”按钮的单击事件
    }
    else if (dialog.Result == DialogResult.No)
    {
        // 处理“否”按钮的单击事件
    }
}
