有关Windows窗体的初始化错误

Question

我在编写一个窗体窗体应用程序，并设法从窗体编码中删除所有错误。然而，当我试图启动应用程序，我得到异常：

抛出异常：“System.TypeInitializationException”在国防部注2.0.exe

附加信息：为“Mod_Note_2._0.Form1的类型初始'抛出了一个例外。

窗体的代码如下：

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

namespace Mod_Note_2._0 
{ 
    public partial class Form1 : Form 
    { 
    //Defines variables 

    public static string moduleTitle; 
    public static string[] codRetr = Directory.GetFiles("" , "*code.txt"); 
    public static string[] notes; 
    public static int i = 0; 
    public static List<string> codDrop; 
    public string[] codDropT; 

    public Form1() 
    { 
     InitializeComponent(); 
    } 

    private void programmingAndDataStructureToolStripMenuItem_Click(object sender, EventArgs e) 
    { 
     moduleTitle = "CMP1127M"; 
     SetTextBoxes item = new SetTextBoxes(); 
     item.moduleTitle1 = moduleTitle; 
    } 

    private void textBox1_TextChanged(object sender, EventArgs e)

    } 

    private void AssignBox_TextChanged(object sender, EventArgs e) 
    {

    } 

    private void modulesToolStripMenuItem_DropDownItemClicked(object sender, ToolStripItemClickedEventArgs e) 
    { 

    } 

    //Puts the information into text boxes 
    private class SetTextBoxes

     public SetTextBoxes() 
     { 
      Form1 frm = new Form1(); 
      notesLoc = moduleTitle + "N"; 

      modNoLocation = moduleTitle1 + "code.txt";

      //Resets the Notes array 
      Array.Clear(notes, 0, 1000000); 

      //Retrieves and sets the notes 
      notes = Directory.GetFiles("", notesLoc); 

     } 


    } 

    private void modulesToolStripMenuItem_Click(object sender, EventArgs e)

    } 



    private void modulesToolStripMenuItem_DropDownOpened_1(object sender, EventArgs e)

     i = 0; 

     foreach (string s in codRetr) 
     { 
      codDrop.Add(s); 
     } 

     codDropT = codDrop.ToArray(); 
    } 



    private void button1_Click(object sender, EventArgs e) 
    { 
     Form3 form3 = new Form3(); 
     form3.Show(); 
    }

}

Answer 1

这是该行导致异常：

public static string[] codRetr = Directory.GetFiles("" , "*code.txt"); 

GetFiles的，如果你想在当前目录下，你可以把第一个参数应该是路径

“”

所以你的行应该是： public static string [] codRetr = Directory.GetFiles（“。”，“* code.txt”）;
