我有以下四个测试,当我运行它时,最后一个测试挂起,我的问题是为什么会发生这种情况:

[Test]
public void CheckOnceResultTest()
{
    Assert.IsTrue(CheckStatus().Result);
}

[Test]
public async void CheckOnceAwaitTest()
{
    Assert.IsTrue(await CheckStatus());
}

[Test]
public async void CheckStatusTwiceAwaitTest()
{
    Assert.IsTrue(await CheckStatus());
    Assert.IsTrue(await CheckStatus());
}

[Test]
public async void CheckStatusTwiceResultTest()
{
    Assert.IsTrue(CheckStatus().Result); // This hangs
    Assert.IsTrue(await CheckStatus());
}

private async Task<bool> CheckStatus()
{
    var restClient = new RestClient(@"https://api.test.nordnet.se/next/1");
    Task<IRestResponse<DummyServiceStatus>> restResponse = restClient.ExecuteTaskAsync<DummyServiceStatus>(new RestRequest(Method.GET));
    IRestResponse<DummyServiceStatus> response = await restResponse;
    return response.Data.SystemRunning;
}

我将此扩展方法用于restsharp RestClient:

public static class RestClientExt
{
    public static Task<IRestResponse<T>> ExecuteTaskAsync<T>(this RestClient client, IRestRequest …
