要使用Python ScriptEngine获取C#中的所有局部变量名称和值,可以通过以下步骤实现:
pip install py4j
。py4j
库来连接到C#的ScriptEngine。示例代码如下:from py4j.java_gateway import JavaGateway
# 连接到C#的ScriptEngine
gateway = JavaGateway()
# 获取C#中的ScriptEngine对象
script_engine = gateway.entry_point.getScriptEngine()
# 获取所有局部变量名称和值
locals_dict = script_engine.getLocals()
# 打印局部变量名称和值
for name, value in locals_dict.items():
print(f"变量名:{name},值:{value}")
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Runtime.InteropServices;
using System.Reflection;
namespace ScriptEngineExample
{
public class ScriptEngine
{
// 定义一个方法,用于获取局部变量
public Dictionary<string, object> GetLocals()
{
Dictionary<string, object> locals = new Dictionary<string, object>();
// 获取当前方法的局部变量
var frame = new System.Diagnostics.StackFrame(1);
var method = frame.GetMethod();
var localsInfo = method.GetMethodBody().LocalVariables;
// 遍历局部变量,获取名称和值
foreach (var localInfo in localsInfo)
{
var localName = localInfo.Name;
var localValue = frame.GetMethod().Invoke(null, null);
locals.Add(localName, localValue);
}
return locals;
}
}

public class ScriptEngineEntryPoint
{
private ScriptEngine scriptEngine;
public ScriptEngineEntryPoint()
{
scriptEngine = new ScriptEngine();
}
// 暴露ScriptEngine对象给Python脚本调用
public ScriptEngine GetScriptEngine()
{
return scriptEngine;
}
}
}
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Runtime.InteropServices;
namespace ScriptEngineExample
{
class Program
{
static void Main(string[] args)
{
// 创建ScriptEngineEntryPoint对象
var entryPoint = new ScriptEngineEntryPoint();
// 将ScriptEngineEntryPoint对象注册为COM组件
var comObject = (object)entryPoint;
var comType = Marshal.GetComInterfaceForObject(comObject, typeof(ScriptEngineEntryPoint));
var comId = Guid.NewGuid().ToString("B");
var comRegistration = string.Format(@"SOFTWARE\Classes\Interface\{0}", comId);
Microsoft.Win32.Registry.ClassesRoot.CreateSubKey(comRegistration);
Microsoft.Win32.Registry.SetValue(comRegistration, "", comType.ToString("B"), Microsoft.Win32.RegistryValueKind.String);
// 启动Python脚本,并传递COM组件的注册ID
var process = new System.Diagnostics.Process();
process.StartInfo.FileName = "python";
process.StartInfo.Arguments = string.Format("script.py {0}", comId);
process.Start();
process.WaitForExit();
}
}
}
py4j
库连接到C#的ScriptEngine,并调用getLocals()
方法获取局部变量名称和值。注意:以上代码示例中,使用了py4j
库来实现Python与C#之间的通信。这是一种常用的方法,但并不是唯一的实现方式。根据具体需求,也可以使用其他方法来实现Python与C#的通信。
