C# 如何在下面的代码段中调用静态异步函数

这里Wait（）返回viod，因此我无法从这里返回任何内容。但我必须添加等待以完成任务。

---

任何人都可以指导我如何获取函数的响应，或者获取响应的其他方法是什么。

要获取函数的响应，请将返回类型更改为

任务

，并返回响应

鉴于响应是唯一需要等待的东西，您可以删除

async

键，然后返回响应任务

ServiceConnect.InvokeRequestResponseService("xyz").Wait();

ServiceConnect.InvokeRequestResponseService("xyz").Wait();

public static Task<HttpResponseMessage> InvokeRequestResponseService( string pstrRequest)
{
    ServiceConnect objServiceConnect = new ServiceConnect();
    using (var client = new HttpClient())
    {
        var scoreRequest = new
        {
            Inputs = new Dictionary<string, InputOutputTable>() {
                {
                    "input1",
                    new InputOutputTable()
                    {
                        ColumnNames = new string[] {"Assignment group", "Short description"},
                        Values = new string[,] {  { "", pstrRequest },  { "", "" },  }
                    }
                },
            },
            GlobalParameters = new Dictionary<string, string>()
            {
            }
        };
        const string apiKey = "Some API Key"; // Replace this with the API key for the web service
        client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", apiKey);

        client.BaseAddress = new Uri("Some Uri");

        // WARNING: The 'await' statement below can result in a deadlock if you are calling this code from the UI thread of an ASP.Net application.
        // One way to address this would be to call ConfigureAwait(false) so that the execution does not attempt to resume on the original context.
        // For instance, replace code such as:
        //      result = await DoSomeTask()
        // with the following:
        //      result = await DoSomeTask().ConfigureAwait(false)

        return client.PostAsJsonAsync("", scoreRequest);
    }
}

HttpResponseMessage response = await ServiceConnect.InvokeRequestResponseService("xyz");
