C#:“'System.InvalidOperationException' 类型的第一次机会异常"

C# : quot;A first chance exception of type #39;System.InvalidOperationException#39;quot;(C#:“System.InvalidOperationException 类型的第一次机会异常)

问题描述

在 C# 中进行类分配时，我遇到了一个程序崩溃，没有任何错误(除了在 VS2010 的调试窗口中写入的内容).这是导致崩溃的典型代码:

Working on a class assignment in C#, I came across a program crash without any error (except what's written in VS2010's debug window). Here is the typical code causing the crash :

public partial class Test : Form
{
    public Test()
    {
        InitializeComponent();
    }

    private void Test_Load(object sender, EventArgs e)
    {
        ColumnHeader header;

        header = new ColumnHeader();
        header.Text = "#";
        header.TextAlign = HorizontalAlignment.Center;
        header.Width = 30;
        listView1.Columns.Add(header);

        TimerCallback tcb = this.UpdateListView;

        System.Threading.Timer updateTimer = new System.Threading.Timer(tcb, null, 0, 1000);
    }

    public void UpdateListView(object obj)
    {
        ListViewItem item;
        listView1.Items.Clear();

        for (int i = 0; i < 10; i++)
        {
            item = new ListViewItem(i.ToString());

            listView1.Items.Add(item);
        }

    }
}

...我在这里错过了什么?

... what am I missing here?

** 编辑 **

没有错误，程序只是结束，就像我调用 System.Environment.Exit(0);

There's no error, the program just ends like if I would call System.Environment.Exit(0);

A first chance exception of type 'System.InvalidOperationException' occurred in System.Windows.Forms.dll
The program '[4644] ProgramTest.vshost.exe: Managed (v4.0.30319)' has exited with code 0 (0x0).
The program '[4644] ProgramTest.vshost.exe: Program Trace' has exited with code 0 (0x0).

推荐答案

如果在异常窗口(Ctrl+Alt+E 在 Visual Studio 中)，那么当您在调试时抛出异常时执行应该中断.

If you check Thrown for Common Language Runtime Exception in the break when an exception window (Ctrl+Alt+E in Visual Studio), then the execution should break while you are debugging when the exception is thrown.

这可能会让您对正在发生的事情有所了解.

This will probably give you some insight into what is going on.
