C＃表格立即关闭

Question

突然我的表单窗口在应用程序启动后就开始关闭。输出窗口中没有任何提示可能导致它的提示，也没有发生任何错误。有人有任何想法吗？

我已经提供给表单的类。

using System; 
using System.Collections.Generic; 
using System.ComponentModel; 
using System.Data; 
using System.Drawing; 
using System.Linq; 
using System.Text; 
using System.Windows.Forms; 

namespace ProjectBoardManagement { 
    public partial class CreateBoard : Form { 

    Functions funcs = new Functions(); 

    public CreateBoard() { 
     InitializeComponent(); 
    } 

    private void CreateBoardButton_Click(object sender, EventArgs e) { 
     String BoardName = BoardNameText.Text; 
     String Pages = ""; 
     String Labels = ""; 
     foreach (ListViewItem i in PageNameList.Items) { 
     Pages = (Pages + i.Name.ToString() + ","); 
     } 

     foreach (ListViewItem i in LabelNameList.Items) { 
     Labels = (Labels + i.Name.ToString() + ","); 
     } 

     String BoardFile = ("board_" + BoardName + ".txt"); 
     funcs.SaveSetting(BoardFile, "name", BoardName); 
     funcs.SaveSetting(BoardFile, "pages", Pages); 
     funcs.SaveSetting(BoardFile, "labels", Labels); 

     FormManagement.CreateBoard.Hide(); 
     FormManagement.BoardList.LoadBoardList(); 
    } 

    private void PageNameButtonAdd_Click(object sender, EventArgs e) { 
     String pagename = PageNameText.Text; 
     if (pagename != "") { 
     PageNameList.Items.Add(pagename); 
     } 
     PageNameText.Text = ""; 
    } 

    private void LabelNameButtonAdd_Click(object sender, EventArgs e) { 
     String labelname = LabelNameText.Text; 
     if (labelname != "") { 
     LabelNameList.Items.Add(labelname); 
     } 
     LabelNameText.Text = ""; 
    } 
    } 
}

明显的第一件事 - 在调试模式下运行它，并停止对所有异常执行。这应该给你足够的信息如何从那里去。

否则Functions funcs = new Functions();看起来很可疑。
