如何:在 Winform 动态启动、控制台命令行?
需求
winForm 程序输出类型为 windows 程序(不是命令行程序)
在运行时想输入一些信息编译开发调试,如何实现这一功能
解答:
AllocConsole、FreeConsole 这两个 API 可以在任何时候调用和关闭 命令行。
代码演示:
API 部分
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.InteropServices;
namespace WindowsFormsApplication1
{
public partial class NativeMethods {
/// <summary>
/// 启动控制台
/// </summary>
/// <returns></returns>
[DllImport("kernel32.dll")]
public static extern bool AllocConsole();
/// <summary>
/// 释放控制台
/// </summary>
/// <returns></returns>
[DllImport("kernel32.dll")]
public static extern bool FreeConsole();
}
}
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.InteropServices;
namespace WindowsFormsApplication1
{
public partial class NativeMethods {
/// <summary>
/// 启动控制台
/// </summary>
/// <returns></returns>
[DllImport("kernel32.dll")]
public static extern bool AllocConsole();
/// <summary>
/// 释放控制台
/// </summary>
/// <returns></returns>
[DllImport("kernel32.dll")]
public static extern bool FreeConsole();
}
}
启动参数的实现
using System;
using System.Collections.Generic;
using System.Linq;
using System.Windows.Forms;
using System.Runtime.InteropServices;
using System.Diagnostics;
namespace WindowsFormsApplication1
{
static class Program
{
/// <summary>
/// 应用程序的主入口点。
/// </summary>
[STAThread]
static void Main(string[] args)
{
try
{
if(args.Length > 0 && args[0].ToLower() == "-c")
{//通过命令行 xxxx.exe -c 参数启动,Console
//注意:不用 Main(string[] args)、System.Environment.GetCommandLineArgs(); 也可以取得命令行参数在任何地方
//启动
NativeMethods.AllocConsole();
Console.WriteLine("控制台以启动");
}
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1());
}
finally
{
//关闭 (如果在这个位置其实写不写都行了)
NativeMethods.FreeConsole();
}
}
}
}
using System.Collections.Generic;
using System.Linq;
using System.Windows.Forms;
using System.Runtime.InteropServices;
using System.Diagnostics;
namespace WindowsFormsApplication1
{
static class Program
{
/// <summary>
/// 应用程序的主入口点。
/// </summary>
[STAThread]
static void Main(string[] args)
{
try
{
if(args.Length > 0 && args[0].ToLower() == "-c")
{//通过命令行 xxxx.exe -c 参数启动,Console
//注意:不用 Main(string[] args)、System.Environment.GetCommandLineArgs(); 也可以取得命令行参数在任何地方
//启动
NativeMethods.AllocConsole();
Console.WriteLine("控制台以启动");
}
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1());
}
finally
{
//关闭 (如果在这个位置其实写不写都行了)
NativeMethods.FreeConsole();
}
}
}
}
程序实现
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void btnOpenConsole_Click(object sender, EventArgs e)
{
//开启控制台
NativeMethods.AllocConsole();
}
private void btnCloseConsole_Click(object sender, EventArgs e)
{
//关闭控制台
NativeMethods.FreeConsole();
}
private void btnOut_Click(object sender, EventArgs e)
{
//模拟输出
Console.WriteLine(textBox1.Text);
}
}
}
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void btnOpenConsole_Click(object sender, EventArgs e)
{
//开启控制台
NativeMethods.AllocConsole();
}
private void btnCloseConsole_Click(object sender, EventArgs e)
{
//关闭控制台
NativeMethods.FreeConsole();
}
private void btnOut_Click(object sender, EventArgs e)
{
//模拟输出
Console.WriteLine(textBox1.Text);
}
}
}
