背景:几个月前,我得到了一个自由职业者编写的桌面应用程序的代码。此后,这位自由职业者关闭了他的账户。在过去的几天里,我一直在努力学习和破译已经编写的代码。我基本上是一个 C# 新手,并且正在用 Udemy C# 课程自学。
问题:当应用程序启动时,它显示一个启动画面。我可以在启动屏幕正确显示的发布模式下运行应用程序。但是在设置中勾选了公共语言运行时异常的调试模式下,我得到了一个异常。详情如下。
System.Threading.ThreadAbortException occurred
HResult=-2146233040
Message=Thread was being aborted.
StackTrace:

at CamCon.MainForm.StartSplash() in E:\Freelance\CamArd\App_C# (2020.03.04)\CamCon\MainForm.cs:line 289
InnerException:
这些是相关的代码片段:
public MainForm()
{
InitializeComponent();
//show splash screen for 2.5seconds
Thread t = new Thread(new ThreadStart(StartSplash));
t.Start();
Thread.Sleep(2500);
t.Abort();
}
和:
private void StartSplash()
{
Application.Run(new SplashForm()); // Exception happens here. This is MainForm.cs:line 289
}
和:
namespace CameraControl
{
partial class SplashForm
{
private System.ComponentModel.IContainer components = null;
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}

((System.ComponentModel.ISupportInitialize)(this.pictureBox1)).BeginInit();
this.SuspendLayout();

this.pictureBox1.TabIndex = 0;
this.pictureBox1.TabStop = false;
//

this.ControlBox = false;
this.Controls.Add(this.pictureBox1);
this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
this.Name = "SplashForm";
this.ShowIcon = false;
this.StartPosition = System.Windows.Forms.FormStartPosition.CenterScreen;
this.Text = "SplashForm";
((System.ComponentModel.ISupportInitialize)(this.pictureBox1)).EndInit();
this.ResumeLayout(false);
}
#endregion
private System.Windows.Forms.PictureBox pictureBox1;
}
}
请求:任何人都可以帮助并建议我应该看什么,以纠正这个异常;这样它就不会在应用程序的其他地方回来咬我(而且我在其他地方也遇到了一些问题,但那是以后再说)?
提前谢谢了!
