在C＃中異步運行IronPython腳本

Question

在C＃4.0和IronPython 2.6中，是否可以在自己的線程中執行python腳本？ 我想在傳遞一些事件處理程序對象之後生成腳本，以便它可以在運行時更新GUI。

Answer 1

我會用一個Task：

ScriptEngine engine = ...; 
// initialize your script and events 

Task.Factory.StartNew(() => engine.Execute(...)); 

IronPython的腳本，然後在一個單獨的線程上運行。確保您的事件處理程序在更新GUI時使用適當的同步機制。

Answer 2

您可以使用後臺工作器在單獨的線程上運行腳本。然後使用ProgressChanged和RunWorkerCompleted事件處理程序更新ui。

BackgroundWorker worker; 
    private void RunScriptBackground() 
    { 
    string path = "c:\\myscript.py"; 
    if (File.Exists(path)) 
    {    
     worker = new BackgroundWorker(); 
     worker.DoWork += new DoWorkEventHandler(bw_DoWork); 
     worker.ProgressChanged += new ProgressChangedEventHandler(bw_ProgressChanged); 
     worker.RunWorkerCompleted += new RunWorkerCompletedEventHandler(bw_RunWorkerCompleted); 
     worker.RunWorkerAsync(); 
    } 
    } 

    private void bw_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) 
    { 
    // handle completion here 
    } 

    private void bw_ProgressChanged(object sender, ProgressChangedEventArgs e) 
    { 
    // handle progress updates here 
    } 

    private void bw_DoWork(object sender, DoWorkEventArgs e) 
    { 
    // following assumes you have setup IPy engine and scope already 
    ScriptSource source = engine.CreateScriptSourceFromFile(path); 
    var result = source.Execute(scope); 
    }
