如何暂停或停止"CSharpScript"跑步? [英] How to pause or stop "CSharpScript" running?

问题描述

我在应用程序中使用Roslyn的脚本API，代码片段如下:

I'm using Roslyn's scripting API in my application, code snippet as following:

public class ScriptEngine
{
    public static string CodeText;
    public static event Action<string[]> CompileErrorEvent;

    public static async Task<bool> RunScriptAsync(CancellationToken ct)
    {
        try
        {
            var scriptResult = await CSharpScript.RunAsync(CodeText, null, new ScriptHost(), null, ct);
            return true;
        }
        catch (Microsoft.CodeAnalysis.Scripting.CompilationErrorException ex)
        {
             List<string> result = new List<string>();

             foreach (var item in ex.Diagnostics)
             {
                 result.Add(item.ToString());
             }

             if (result.Count > 0)
             {
                 CompileErrorEvent?.Invoke(result.ToArray());
             }

             return false;
         }
         catch (Exception ex)
         {
             IMCP_Base.Dialog.Show.SimpleError("脚本运行", ex.Message, "修改脚本");
             return false;
         }
     } 
     .......
}

public static CancellationTokenSource ScriptCTS;

private async void btnScriptRun_ItemClick(object sender, ItemClickEventArgs e)
{
    ScriptCTS = new CancellationTokenSource();

    if (CheckScriptEditorIsNotNull())
    {
         Script.ScriptEngine.CodeText = ScriptEditor.GetCode();
         bool runSuccess = await Script.ScriptEngine.RunScriptAsync(ScriptCTS.Token);
    }
}   

private void btnScriptStop_ItemClick(object sender, ItemClickEventArgs e)
{
    ScriptCTS?.Cancel();
}

CSharpScript.RunAsync方法运行良好，但是当我单击ScriptStop按钮时，ScriptCTS?.Cancel()无法取消正在运行的脚本.

CSharpScript.RunAsync method runs well, but when I click ScriptStop button, ScriptCTS?.Cancel() can't cancel running script.

如何停止或暂停脚本的运行?

推荐答案

如果您想要脚本中的取消点，则可以使用 globals ，然后传入CancelationToken，然后您可以在脚本中签入以进行取消.

If you want cancellation points within your scripts, you can use globals, and pass in the CancelationToken, which you can then check in your scripts for cancellation.
