我希望为文件中的每一行添加一个按钮.到目前为止我的代码是:

StreamReader menu = new StreamReader("menu.prefs");
int repetition = 0;

while(!menu.EndOfStream)
{
    Button dynamicbutton = new Button();
    dynamicbutton.Click += new System.EventHandler(menuItem_Click);
    dynamicbutton.Text = menu.ReadLine();
    dynamicbutton.Visible = true;
    dynamicbutton.Location = new Point(4+repetition*307, 4);
    dynamicbutton.Height = 44;
    dynamicbutton.Width = 203;
    dynamicbutton.BackColor = Color.FromArgb(40,40,40);
    dynamicbutton.ForeColor = Color.White;
    dynamicbutton.Font = new Font("Lucida Console", 16);
    dynamicbutton.Show();
    menuPanel.Controls.Add(dynamicbutton);
    repetition++;
    MessageBox.Show(dynamicbutton.Location.ToString());
}
menu.Close();

问题是只创建了第一个控件.

我有一个命令行程序正在运行,我想向它发送其他命令(IE一旦它已经运行)我怎么能在C#中执行此操作？

想不出更好的头衔.我只想让别人告诉我这段代码有什么问题:

public AddressChooser(string argstreet, string argsuburb, string argcountry, string argstate, string argunit, int argstreetNumber, int argpostCode)
        {
            streetNameBox.Text = argstreet;
            suburbBox.Text = argsuburb;
            countryBox.Text = argcountry;
            stateBox.Text = argstate;
            unitBox.Text = argunit;
            streetNumberBox.Value = argstreetNumber;
            postCodeBox.Value = argpostCode;
            InitializeComponent();
            cancel.DialogResult = DialogResult.Cancel;
            save.DialogResult = DialogResult.OK;
        }

返回的错误是:

  System.NullReferenceException was unhandled
  Message=Object reference not set to an instance of an object.
  Source=MultipleForms
  StackTrace:
       at MultipleForms.AddressChooser..ctor(String argstreet, String argsuburb, String argcountry, String argstate, String argunit, Int32 argstreetNumber, Int32 argpostCode) in C:\Users\Yoshie\Local Settings\Documents\Visual …

我不能使用GetCultures,从我可以告诉它返回一个空白列表.

private void AddressChooser_Load(object sender, EventArgs e)
    {
        MessageBox.Show("Form load event successfully triggered") //Debug message - This appears at runtime
        foreach (string country in GetCountryList())
        {
            MessageBox.Show(country); //Debug message - This does not appear at runtime!!
            countryBox.Items.Clear();
            countryBox.Items.Add(country);
        }
    }

    public static List<string> GetCountryList()
    {
        MessageBox.Show("Function has been triggered successfully"); //Debug message - This appears at runtime
        List<string> cultureList = new List<string>();
        CultureInfo[] cultures = CultureInfo.GetCultures(CultureTypes.AllCultures & ~CultureTypes.NeutralCultures);
        foreach (CultureInfo culture in cultures)
        {
            RegionInfo region = new RegionInfo(culture.LCID);
            if …
