我正在开发一个主要是Windows窗体应用程序的迁移工具。我想要做的是提供将应用程序作为一种命令行实用程序运行的能力,其中可以传入参数并且完全没有GUI的迁移。这似乎很直接,我的应用程序的入口点如下所示:
[STAThread]
static void Main(string[] args)
{
if (args.Length == 0)
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new MainWindow());
}
else
{
//Command Line Mode
Console.WriteLine("In Command Line Mode");
Console.ReadLine();
}
}
我遇到的问题是,当执行进入else块时,文本不会在命令提示符处写回用户,这是有问题的,因为我想在命令提示符下更新用户,因为各种执行完成。我可以轻松编写一个独立的控制台应用程序,但我希望提供一个允许给定方案的不同类型的条目的单个工具。我正在寻求做什么,如果是的话,它是如何实现的?
谢谢!

关键是从kernel32.dll调用AllocConsole

通常的模式是将逻辑写入您可以从可视UI或命令行应用程序调用的类库。
例如,如果您在UI上接受了“宽度”,“高度”和“深度”,然后计算了音量,则可以将计算放入类库中。
所以你有一个Console应用程序接受三个参数,或者一个带有三个输入的表单应用程序,在这两种情况下,它们都会进行相同的调用......
var volumeCalculations = new VolumeCalculations();
var volume = volumeCalculations.GetVolume(width, height, depth);
控制台应用程序非常薄,表单应用程序非常精简,因为他们所做的就是获取传递给类库的输入。

这是完成的可运行示例。编译:
csc RunnableForm.cs RunnableForm.Designer.cs
RunnableForm.cs:
using System;
using System.Linq;
using System.Windows.Forms;
namespace Test
{
public partial class RunnableForm : Form
{
public RunnableForm()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
MessageBox.Show("bang!");
}
[STAThread]
static void Main()
{
string[] args = Environment.GetCommandLineArgs();
// We'll always have one argument (the program's exe is args[0])
if (args.Length == 1)
{
// Run windows forms app
Application.Run(new RunnableForm());
}
else
{
Console.WriteLine("We'll run as a console app now");
Console.WriteLine("Arguments: {0}", String.Join(",", args.Skip(1)));
Console.Write("Enter a string: ");
string str = Console.ReadLine();
Console.WriteLine("You entered: {0}", str);
Console.WriteLine("Bye.");
}
}
}
}
RunnableForm.Designer.cs:
namespace Test
{
partial class RunnableForm
{
/// <summary>
/// Required designer variable.
/// </summary>
private System.ComponentModel.IContainer components = null;
/// <summary>
/// Clean up any resources being used.
/// </summary>
/// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
#region Windows Form Designer generated code

{

this.ResumeLayout(false);
