我有这样的方法:

public async Task<MyResult> GetResult()
{
    MyResult result = new MyResult();

    foreach(var method in Methods)
    {
        string json = await Process(method);

        result.Prop1 = PopulateProp1(json);
        result.Prop2 = PopulateProp2(json);

    }

    return result;
}

然后我决定使用Parallel.ForEach:

public async Task<MyResult> GetResult()
{
    MyResult result = new MyResult();

    Parallel.ForEach(Methods, async method =>
    {
        string json = await Process(method);    

        result.Prop1 = PopulateProp1(json);
        result.Prop2 = PopulateProp2(json);
    });

    return result;
}

但现在我有一个错误:

在异步操作仍处于挂起状态时完成异步模块或处理程序.
