兩光程式筆記本

原先的程式碼如下，產生deadlock

private void button1_click()
{    
    //產生deadlock
    ProductUpdateInfo pdUpate = Query.GetAppUpdateInfo(TokenText.Text, 1598, "1.21.525.1").GetAwaiter().GetResult();
}

private async Task<T> QeuryActionGeneric<T>(string token, object queryObject) 
{ 
    T result = default(T); 
    var request = new HttpRequestMessage 
    { 
        Method = HttpMethod.Post, 
        Content = new StringContent(JsonConvert.SerializeObject(queryObject), Encoding.UTF8, "application/json") 
    }; 
    using (var response = await Client.SendAsync(request)) 
    { 
        response.EnsureSuccessStatusCode(); 
        var responseString = await response.Content.ReadAsStringAsync(); 
        result = JsonConvert.DeserializeObject<T>(responseString);  
    } 
     
    return result; 
}

修改後，加上.ConfigureAwait(false)

private async Task<T> QeuryActionGeneric<T>(string token, object queryObject) 
{ 
    T result = default(T); 
    var request = new HttpRequestMessage 
    { 
        Method = HttpMethod.Post, 
        Content = new StringContent(JsonConvert.SerializeObject(queryObject), Encoding.UTF8, "application/json") 
    }; 
    using (var response = await Client.SendAsync(request).ConfigureAwait(false)) 
    { 
        response.EnsureSuccessStatusCode(); 
        var responseString = await response.Content.ReadAsStringAsync().ConfigureAwait(false); 
        result = JsonConvert.DeserializeObject<T>(responseString);   
    } 
     
    return result; 
}
