上两篇IronPython脚本的文章介绍了与C#紧密结合的示例,这里还将提供一个与C#结合更紧密的示例,直接调用C#编写的DLL。
我们还是沿用了上篇文章的代码(其实这里可以直接使用IronPython调试器进行联调了,没有必要再嵌入到C#了)
注意:scriptEngine.AddToPath(Application.StartupPath); 这句代码比较关键,设定dll文件所在的目录。
using
System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using IronPython.Hosting;
namespace TestIronPython
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click( object sender, EventArgs e)
{
PythonEngine scriptEngine = new PythonEngine();
scriptEngine.AddToPath(Application.StartupPath);
scriptEngine.Execute(textBox1.Text);
}
}
}
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using IronPython.Hosting;
namespace TestIronPython
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click( object sender, EventArgs e)
{
PythonEngine scriptEngine = new PythonEngine();
scriptEngine.AddToPath(Application.StartupPath);
scriptEngine.Execute(textBox1.Text);
}
}
}
开始编写可供IronPython脚本调用的DLL,我们编写了两个类,一个提供静态函数访问,另一个提供属性和普通函数访问,以区别在IronPython脚本不同调用的方式。代码如下:
using
System;
using System.Collections.Generic;
using System.Text;
namespace IronPython_TestDll
{
public class TestDll
{
public static int Add( int x, int y)
{
return x + y;
}
}
public class TestDll1
{
private int aaa = 11 ;
public int AAA
{
get { return aaa; }
set { aaa = value; }
}
public void ShowAAA()
{
global ::System.Windows.Forms.MessageBox.Show(aaa.ToString());
}
}
}
using System.Collections.Generic;
using System.Text;
namespace IronPython_TestDll
{
public class TestDll
{
public static int Add( int x, int y)
{
return x + y;
}
}
public class TestDll1
{
private int aaa = 11 ;
public int AAA
{
get { return aaa; }
set { aaa = value; }
}
public void ShowAAA()
{
global ::System.Windows.Forms.MessageBox.Show(aaa.ToString());
}
}
}
下面再让我们看看IronPython脚本中的代码吧:
import
clr
clr.AddReferenceByPartialName( " System.Windows.Forms " )
clr.AddReferenceByPartialName( " System.Drawing " )
from System.Windows.Forms import *
from System.Drawing import *
clr.AddReferenceToFile( "I ronPython_TestDll.dll " )
from IronPython_TestDll import *
a = 12
b = 6
c = TestDll.Add(a,b)
MessageBox.Show(c.ToString())
td = TestDll1()
td.AAA = 100
td.ShowAAA()
clr.AddReferenceByPartialName( " System.Windows.Forms " )
clr.AddReferenceByPartialName( " System.Drawing " )
from System.Windows.Forms import *
from System.Drawing import *
clr.AddReferenceToFile( "I ronPython_TestDll.dll " )
from IronPython_TestDll import *
a = 12
b = 6
c = TestDll.Add(a,b)
MessageBox.Show(c.ToString())
td = TestDll1()
td.AAA = 100
td.ShowAAA()
比较关键的是这两句:
clr.AddReferenceToFile("TronPython_TestDll.dll") -- 加载DLL文件
from TronPython_TestDll import * -- 导入命名空间
静态方法可以直接调用,普通方法需要先定义类,再访问(和访问IronPython
自己本身的类没有任何区别)。
运行结果如下:
现在你是否对IronPython充满期待和兴趣了吧,动起手来,感受它的强大!
