IronPython2.7 & C# 4.0 互调用备忘-优快云博客

本文介绍了一个使用IronPython与C#进行交互调用的实际案例，演示了如何从C#环境中加载并执行Python脚本，同时展示了数据表操作、方法调用及变量传递的过程。

查了些资料，自己再测试后发现，IronPython已经蛮方便与C#互调用了

{


public class Program
{
    public delegate void OutPut_delegate(object s);

    public string OutPut_instance(object s)
    {
        Console.WriteLine("对象方法调用 OutPut_Pri {0} ", s.ToString());
        return "return 国语 in charp";
    }

    static public void OutPut_static(object s)
    {
        Console.WriteLine("in C# 静态方法 OutPut {0} ", s.ToString());
    }

    static void OutPut(object s)
    {
        Console.WriteLine("C# 委托测试 {0} ", s.ToString()); 
    }

    public int abc;

    static void Main(string[] args)
    {
        OutPut_delegate output = OutPut;
        DataTable dt = new DataTable();
        dt.Columns.Add("count", typeof(int));
        dt.Columns.Add("calc", typeof(int));
        dt.Rows.Add(1, null);

        var engine = Python.CreateEngine(); 
        var runtime = engine.Runtime;
        
        try 
        {
            Program program = new Program();
            dynamic test = runtime.UseFile(@"d:\test.py");
            int abc =100;

            //ref out等方法也不能在python中修改再返回C#，因此要用实体类的方法来传值
            Console.WriteLine("return value is {0}", test.MyFunction(dt, ref abc, output, program));
            foreach (DataRow dr in dt.Rows)
                Console.WriteLine(dr["count"]);
            Console.WriteLine(program.abc);//会发生变化
            Console.WriteLine(abc);//不会发生变化
        }
        catch (Exception ex)
        {
            var eo = engine.GetService<ExceptionOperations>();
            Console.WriteLine(eo.FormatException(ex));
        }
    }
}

}
