我有一个使用C#编写的简单应用程序,该应用程序通过命令行参数接受操作数,并通过退出代码报告成功或失败。通过批处理文件在Windows XP上运行时:
MyProg.exe ...//Snip: Command-line Params ...
echo %errorlevel%;
返回的退出代码是应用程序设置的值。但是,当使用bash脚本在Linux上调用同一应用程序时:
mono MyProg.exe ...//Snip: Command-line Params ...
echo $?;
报告给外壳程序的退出代码始终为零,而不是应用程序设置的值。在单声道修改退出代码之前,有什么方法可以捕获它吗?
我尝试使用
Environment.Exit()
和Application.Exit()
,在此问题上似乎没有区别。同样,应用程序在调用出口函数之前显式设置Environment.ExitCode
。这是一个简单的WinForms应用程序,可重现此行为:
using System;
using System.Drawing;
using System.Windows.Forms;
namespace ConsoleTest
{
public class Form1 : Form
{
private System.Windows.Forms.Button button1;
private System.Windows.Forms.Button button2;
public Form1()
{
#region Create UI Stuff
this.button1 = new System.Windows.Forms.Button();
this.button2 = new System.Windows.Forms.Button();
this.SuspendLayout();
//
// button1
//
this.button1.Location = new System.Drawing.Point(114, 22);
this.button1.Name = "button1";
this.button1.Size = new System.Drawing.Size(75, 23);
this.button1.TabIndex = 0;
this.button1.Text = "ExitZero";
this.button1.UseVisualStyleBackColor = true;
this.button1.Click += new System.EventHandler(this.button1_Click);
//
// button2
//
this.button2.Location = new System.Drawing.Point(114, 70);
this.button2.Name = "button2";
this.button2.Size = new System.Drawing.Size(75, 23);
this.button2.TabIndex = 0;
this.button2.Text = "ExitOne";
this.button2.UseVisualStyleBackColor = true;
this.button2.Click += new System.EventHandler(this.button2_Click);
//
// Form1
//
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.ClientSize = new System.Drawing.Size(310, 136);
this.Controls.Add(this.button2);
this.Controls.Add(this.button1);
this.Name = "Form1";
this.Text = "Form1";
this.ResumeLayout(false);
#endregion
}
private void button1_Click(object sender, EventArgs e)
{
Environment.ExitCode = 0;
//Environment.Exit(0);
Application.Exit();
}
private void button2_Click(object sender, EventArgs e)
{
Environment.ExitCode = 1;
//Environment.Exit(1);
Application.Exit();
}
}
}
最佳答案
Mono不重写任何内容。我的测试应用程序:
pakrym@ubuntu:/home/pakrym# cat exit.cs
class Program
{
public static void Main()
{
System.Environment.Exit(1);
}
}
pakrym@ubuntu:/home/pakrym# mono ./exit.exe
pakrym@ubuntu:/home/pakrym# echo $?
1
pakrym@ubuntu:/home/pakrym# mono --version
