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

本文介绍了C＃：“类型为'System.InvalidOperationException'的第一次机会异常”的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

在C＃中的类分配，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）。下面是导致崩溃的典型代码：

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 = Horizo​​ntalAlignment.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）; } } }

没有错误，程序只是结束就好像我会调用 System.Environment.Exit（0）;

System.Windows.Forms.dll中发生类型为System.InvalidOperationException的第一次机会异常程序'[4644] ProgramTest.vshost.exe ：Managed（v4.0.30319）'已退出，代码为0（0x0）。 程序'[4644] ProgramTest.vshost.exe：Program Trace'已退出，代码为0（0x0）。如果您选中 Thrown （ Ctrl + Alt +）中的中断中的 E 在Visual Studio中），那么在调试时抛出异常时，执行应该会中断。

这可能会让您深入了解发生了什么。

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); } } }

... what am I missing here?

** EDIT **

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).

解决方案

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.

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