有没有办法保存LINQPad.Util.Compile的结果并重新运行它很长一段时间

Question

我有一个脚本Web服务,它将从内容管理系统下载并运行linqpad .linq程序.我目前正在做类似下面的代码.有没有办法保存LINQPad.Util.Compile的结果并将其存储在某处,以便我可以使用它直到.linq文件已更改？现在我认为它每次都在重新编译,并产生许多编译文件夹.

public static object DownloadAndRunScript(string scriptFilePath, object args)
{
     var compiledScript = LINQPad.Util.Compile(scriptFilePath, true);
     var queryExecutorResult = compiledScript.Run(LINQPad.QueryResultFormat.Text, args);
     return (object)queryExecutorResult.ReturnValue;
}

您可以相当轻松地为此编写缓存函数.像这样的东西:

static Dictionary<string, Tuple<DateTime, QueryCompilation>> _cache
    = new Dictionary<string, System.Tuple<System.DateTime, QueryCompilation>>();

public static QueryCompilation GetCompilation (string scriptFilePath)
{
    Tuple<DateTime, LINQPad.ObjectModel.QueryCompilation> entry;
    var writeTime = new FileInfo (scriptFilePath).LastWriteTimeUtc;

    lock (_cache)
        if (_cache.TryGetValue (scriptFilePath, out entry) && entry.Item1 == writeTime)
            return entry.Item2;

    var compiledScript = LINQPad.Util.Compile (scriptFilePath, true);

    lock (_cache)
        _cache [scriptFilePath] = Tuple.Create (writeTime, compiledScript);

    return compiledScript;
}
