Question

我有两种形式：

MainForm
SettingsForm

可以想象，MainForm使用Properties.Settings.Default.Path和SettingsForm之类的值应该能够在运行时配置这样的值。

但不知怎的，SettingsForm: Properties.Settings.Default.Save();在应用程序重启后才生效，虽然我正在MainForm: Properties.Settings.Default.Reload();重新加载这些设置

到目前为止，我有这个：

在MainForm.cs：

    // Handles "config button click" => display settings form
    private void configStatusLabel_Click(object sender, EventArgs e)
    {
        SettingsForm form = new SettingsForm();
        form.FormClosed += new FormClosedEventHandler(form_FormClosed);
        form.Show();
    }

    // Callback triggered on Settings form closing
    void form_FormClosed(object sender, FormClosedEventArgs e)
    {
        Properties.Settings.Default.Reload();
    }

    // There are another methods called after form_FormClosed is triggered, for example
    // StremWriter = new StreamWriter(  Properties.Settings.Default.Path)

SettingsForm.cs：

    // Triggered on "Save button click" in Settings form, after changing values
    // Example: Properties.Settings.Default.Path = "C:\\file.txt" 
    private void saveButton_Click(object sender, EventArgs e)
    {
        Properties.Settings.Default.Save();
        Close();
    }

我错过了什么？ 如何实现“按需更改”？

在主窗体中，有几个按钮会触发使用ReloadLog()的{{1}}等功能。所以最后我按照这个顺序执行了函数：

Properties.Settings.Default.Path

Answer 1

private void configStatusLabel_Click(object sender, EventArgs e)
{
    SettingsForm form = new SettingsForm();
    form.FormClosed += new FormClosedEventHandler(form_FormClosed);
    form.FormClosed += (s, e) => { MethodThatAppliesTheSettings(); };
    form.Show();
}

Properties.Settings - 多种形式
