Question

说我有一个python脚本'calculator.py'：

def Add(x,y) :
    return x + y;

我可以像这样实例化一个动态对象：

var runtime = Python.CreateRuntime();
dynamic calculator = runtime.UseFile("calculator.py");
int result = calculatore.Add(1, 2);

是否有类似的简单方法从内存中的字符串实例化计算器？我想得到的是：

var runtime = Python.CreateRuntime();
string script = GetPythonScript();
dynamic calculator = runtime.UseString(script); // this does not exist
int result = calculatore.Add(1, 2);

GetPythonScript（）可能是这样的：

string GetPythonScript() {
   return "def Add(x,y) : return x + y;"
}

Answer 1

你可以这样做：

var engine = Python.CreateEngine();
dynamic calculator = engine.CreateScope();
engine.Execute(GetPythonScript(), calculator);

Answer 2

做这样的事情：

public string Evaluate( string scriptResultVariable, string scriptBlock )
{
    object result;

    try
    {
        ScriptSource source = 
            _engine.CreateScriptSourceFromString( scriptBlock, SourceCodeKind.Statements );

        result = source.Execute( _scope );
    }
    catch ( Exception ex )
    {
        result = "Error executing code: " + ex;
    }

    return result == null ? "<null>" : result.ToString();
}
