Question

我需要以某种方式将jarray转换为c＃中的字节数组，以便我可以显示相应的图像。呼叫是通过RESTful Web服务进行的，作为回应我得到了这个（样本）值：

[255,216,255,224,0,16,74,70,73,70,0,1,1,1,0,96,0,96,0,0,255,219,0,67,0,4,2,3， 3,3,2,4,3,3,3,4,4,4,4,5,9,6,5,5,5,5,11,8,8,6,9,13,11， 13,13,13,11,12,12,14,16,20,17,14,15,19,15,12,12,18,24,18,19,21,22,23,23,23， 14,17,25,27,25,22,26,20,22,23,22,255,219,0,67,1,4,4,4,5,5,5,10,6,6,10,22， 15,12,15,22,22,22,22,22,22,22,22,22,22,22,22,22,22,22,22,22,22,22,22,22,22， 22,22,22,22,22,22,22,22,22,22,22,22,22,22,22,22,22,22,22,22,22,22,22,22,22， 22,22,22,255,192,0,17,8,0,67,0,100,3,1,34,0,2,17,1,3,17,1,255,196,0,31,0,0,1,5， 1,1,1,1,1,1,0,0,0,0,0,0,0,0,1,2,3,4,5,6,7,8,9]

注意：我修剪了值的内容，但这是我得到的数据。现在这就是我获得价值的方式：

                foreach (JObject obj in arr)
                {
                    JArray jar = new JArray();                            
                    jar = obj["Thumbnail"] as JArray;

                }

如何将该值转换为byte []以便我可以在mvc视图中显示图像？在此先感谢Laziale

Answer 1

只需使用String方法和LINQ来获取字节数组：

byte[] bytes = response.Trim('[', ']')
              .Split(',')
              .Select(x => byte.Parse(x))
              .ToArray();

Answer 2

byte[] bytes = responce.Split(',').Select(s => Convert.ToByte(s, 16)).ToArray();

Answer 3

byte[] byteItems = myJArray.Split(',').Select(z => byte.Parse(z)).ToArray();


If you dun't need to split then

byte[] byteItems = myJArray.Select(z => byte.Parse(z)).ToArray();

将jarray转换为c＃中的字节数组
