如何在异步任务方法之外使用局部变量？

Question

如何在此方法之外分配“ip”？这是我第一次在这里提问。

public async Task GetIPAsync()
{
    var client = new HttpClient();
    string response = await client.GetStringAsync(new Uri("https://www.meethue.com/api/nupnp"));
    string ip = JArray.Parse(response).First["internalipaddress"].ToString();        
}

Answer 1

public async Task<string> GetIPAsync()
{
    var client = new HttpClient();
    string response = await client.GetStringAsync(new Uri("https://www.meethue.com/api/nupnp"));
    string ip = JArray.Parse(response).First["internalipaddress"].ToString();
    return ip;
}

// Then to call it, do:
string ip = await GetIPAsync();
