我正在学习如何在控制台应用程序中使用异步函数,但无法使Task.WhenAll等到所有任务完成.以下代码有什么问题？它同步工作.先感谢您.

static void Main(string[] args)
{
    ...
    IncluiValores(...);
    ...
}

static async void IncluiValores(...)
{
    Task<List<int>> res1 = att.GetAIDBAPI(att);
    Task<List<int>> res2 = att.GetAIDBAPI(att2);

    List<int>[] res = await Task.WhenAll(res1, res2);

    ...
}

更新 - 功能定义:

    public async Task<List<int>> GetAIDBAPI(Attributes attributes)
    {

        List<int> results = null;

        Connections client0 = new Connections();
        HttpClient client = client0.OpenAPIConnection(attributes.User[0], attributes.Pwd, attributes.Server, attributes.Chave, attributes.Server2);
        HttpResponseMessage response = await client.PostAsJsonAsync("api/Attributes/ID/Bulk", attributes);

        if (response.IsSuccessStatusCode)
        {
            var content = await response.Content.ReadAsStringAsync();
            results = JsonConvert.DeserializeObject<dynamic>(content).ToObject<List<int>>();
        }
        else
        {
            var content = …
