从 C# Ironpython 调用 .dll 函数
Call .dll function from C# Ironpython
我使用 Ironpython 从 .py 文件创建了一个 .dll。它有 classes 和我想调用以在 c# 中使用的相应函数。我创建了 .dll 以便我可以对用户隐藏源代码。
这是我尝试过的:
ScriptEngine engine = Python.CreateEngine();
scope = engine.CreateScope();
engine.Runtime.LoadAssembly(Assembly.LoadFile(fullPath2DLL));
scope = engine.ImportModule("Simulation");
但是,它找不到 "Simulation"。
此外,我想立即导入整个脚本,这样我就可以调用任何东西,只要 [而不是 class 'Simulation']。
很多事情都可能出错,所以我将只向您展示有效的完整示例。让我们以我在某个示例中获取的 python 代码为例:
MyGlobal = 5
class Customer(object):
"""A customer of ABC Bank with a checking account. Customers have the
following properties:
Attributes:
name: A string representing the customer's name.
balance: A float tracking the current balance of the customer's account.
"""
def __init__(self, name, balance=0.0):
"""Return a Customer object whose name is *name* and starting
balance is *balance*."""
self.name = name
self.balance = balance
def withdraw(self, amount):
"""Return the balance remaining after withdrawing *amount*
dollars."""
if amount > self.balance:
raise RuntimeError('Amount greater than available balance.')
self.balance -= amount
return self.balance
def deposit(self, amount):
"""Return the balance remaining after depositing *amount*
dollars."""
self.balance += amount
return self.balance
现在让我们打开 ipy 并将其编译成 dll:
>>> import clr
>>> clr.CompileModules("path_to.dll", "path_to.py");
现在我们有了 dll。如您所见,python 代码包含 class 定义,我们的目标是在 C# 中创建 class 的实例并调用一些方法。
public class Program {
private static void Main(string[] args) {
ScriptEngine engine = Python.CreateEngine();
engine.Runtime.LoadAssembly(Assembly.LoadFile(@"path_to.dll"));
// note how scope is created.
// "test" is just the name of python file from which dll was compiled.
// "test.py" > module named "test"
var scope = engine.Runtime.ImportModule("test");
// fetching global is as easy as this
int g = scope.GetVariable("MyGlobal");
// writes 5
Console.WriteLine(g);
// how class type is grabbed
var customerType = scope.GetVariable("Customer");
// how class is created using constructor with name (note dynamic keyword also)
dynamic customer = engine.Operations.CreateInstance(customerType, "Customer Name");
// calling method on dynamic object
var balance = customer.deposit(10.0m);
// this outputs 10, as it should
Console.WriteLine(balance);
Console.ReadKey();
}
}
