步骤 5：工作流

定义工作流步骤（执行程序）：

using Microsoft.Agents.AI.Workflows;

// Step 1: Convert text to uppercase
Func<string, string> uppercaseFunc = s => s.ToUpperInvariant();
var uppercase = uppercaseFunc.BindAsExecutor("UppercaseExecutor");

// Step 2: Reverse the string and yield output
class ReverseTextExecutor() : Executor<string, string>("ReverseTextExecutor")
{
    public override ValueTask<string> HandleAsync(string message, IWorkflowContext context, CancellationToken cancellationToken = default)
    {
        return ValueTask.FromResult(string.Concat(message.Reverse()));
    }
}
ReverseTextExecutor reverse = new();

生成并运行工作流：

WorkflowBuilder builder = new(uppercase);
builder.AddEdge(uppercase, reverse).WithOutputFrom(reverse);
var workflow = builder.Build();

await using Run run = await InProcessExecution.RunAsync(workflow, "Hello, World!");
foreach (WorkflowEvent evt in run.NewEvents)
{
    if (evt is ExecutorCompletedEvent executorComplete)
    {
        Console.WriteLine($"{executorComplete.ExecutorId}: {executorComplete.Data}");
    }
}
