在.NET 4中托管控制台应用程序中的工作流程

Question

如何在控制台应用程序中托管工作流程？我搜索了足够多，没有找到任何好的示例。

Answer 1

我很惊讶你找不到一个例子，因为大多数基本的例子都是使用控制台应用程序完成的。例如这一个。

工作流运行时间与主机类型无关，所以像这样的东西在控制台应用程序中工作得很好，或者在ASP.NET或WPF应用程序中工作得很好。

var workflow = new Workflow1(); 
workflow.FirstName = "Maurice"; 
workflow.LastName = "de Beijer"; 

var result = WorkflowInvoker.Invoke(workflow); 
Console.WriteLine(result["Greeting"]); 

Answer 2

我已经做了类似如下，其中“FeedManager”是控制台应用程序，ProcessAllImports和ProcessAllExportFeeds是代码或XAML活动。它简单但运作良好。 希望这有助于...

class FeedManager 
{ 
    static void Main(string[] args) 
    { 
     FeedManager fm = new FeedManager(); 
     fm.Run(args); 
    } 

    private int Run(string[] args) 
    { 
     ProcessAllImports importProcess = new ProcessAllImports(); 
     List<Feed> importFeedSuccesses = new List<Feed>(); 
     List<Feed> importFeedsFailure = new List<Feed>(); 

     ProcessAllExportFeeds exportProcess = new ProcessAllExportFeeds(); 
     List<Feed> exportFeedSuccesses = new List<Feed>(); 
     List<Feed> exportFeedsFailure = new List<Feed>(); 

     try 
     { 
      IDictionary<string, object> importFeedsArgs = new Dictionary<string, object> 
      { 
       { "FeedsSuccess", importFeedSuccesses }, 
       { "FeedsFailure", importFeedsFailure }, 
      }; 
      var importOutput = WorkflowInvoker.Invoke(importProcess, importFeedsArgs); 
      bool importSuccess = (bool)importOutput["Success"]; 
      importFeedSuccesses = (List<Feed>)importOutput["FeedsSuccess"]; 
      importFeedsFailure = (List<Feed>)importOutput["FeedsFailure"]; 

      IDictionary<string, object> exportFeedsArgs = new Dictionary<string, object> 
      { 
       { "FeedsSuccess", exportFeedSuccesses }, 
       { "FeedsFailure", exportFeedsFailure }, 
      }; 
      var exportOutput = WorkflowInvoker.Invoke(exportProcess, exportFeedsArgs); 
      bool exportSuccess = (bool)exportOutput["Success"]; 
      exportFeedSuccesses = (List<Feed>)exportOutput["FeedsSuccess"]; 
      exportFeedsFailure = (List<Feed>)exportOutput["FeedsFailure"]; 

     } 
     catch (Exception e) 
     { 
      return -1; 
     }
