宿主环境内有这样一个数据，如下：

public class MyObject

    {         public int MyValue { get; set; }         public string MyString { get; set; }     }

 

在Activity内访问该对象实例的方法如下：

public sealed class SymbolUser : CodeActivity

    {         protected override void Execute(CodeActivityContext context)         {             SymbolResolver symbolResolver = context.GetExtension<SymbolResolver>();             MyObject obj = symbolResolver["CustomObject"] as MyObject;             Console.WriteLine(obj.MyString);         }

    }

 

宿主的代码如下：

class Program

    {         static void Main(string[] args)         {             WorkflowApplication WFApp = new WorkflowApplication(new Workflow1());             SymbolResolver symbolResolver = new SymbolResolver();             WFApp.Extensions.Add(symbolResolver);             symbolResolver.Add("CustomObject", new MyObject() { MyValue = 1, MyString = "TestString" });             WFApp.Run();             Console.ReadLine();

        }

    }

当SymbolUser Activity执行的时候就可以得到new MyObject()的属性信息了。
