C# int64 列表到字节数组，反之亦然

# 将C# Int64列表转换为字节数组及反向操作的实现

csharp
List int64List = new List { 1234567890123456789, 9876543210987654321 };
List byteArray = new List();
foreach (long number in int64List)
{
    byteArray.AddRange(BitConverter.GetBytes(number));
}

csharp
List resultInt64List = new List();
for (int i = 0; i < byteArray.Count; i += 8)
{
    resultInt64List.Add(BitConverter.ToInt64(byteArray.ToArray(), i));
}
