问题描述
我试图数组从转换的byte []
到为sbyte []
。
下面是我的样品阵列:
字节[]符号= {为0x00,0xFF的,为0x1F ,0x8F,0x80的};
我已经尝试过这样的:
为sbyte [] =签署(为sbyte [])((阵列)的无符号);
不过,这是行不通的。有此操作后,在数组中没有价值。
有谁有一个更好的主意?
为sbyte [] =签署(为sbyte [])(阵列)符号;
此工作,因为字节和为sbyte具有在存储器中的相同的长度,并且可以无需改变被转换内存表现形式。
这方法可能,然而,导致与调试器的一些奇怪的错误。如果你的字节数组不是很大,你可以使用 Array.ConvertAll
代替。
为sbyte [] =签署Array.ConvertAll(无符号,b =>取消选中((为sbyte)b)条);
I tried to convert an Array from byte[]
to sbyte[]
.
Here is my sample Array:
byte[] unsigned = { 0x00, 0xFF, 0x1F, 0x8F, 0x80 };
I already tried this:
sbyte[] signed = (sbyte[])((Array)unsigned);
But it doesn't work. There is no value in the array after this operation.
Does anybody has an better idea?
sbyte[] signed = (sbyte[]) (Array) unsigned;
This works because byte and sbyte have the same length in memory and can be converted without the need to alter the memory representation.
This method might, however, lead to some weird bugs with the debugger. If your byte array is not very big, you can use Array.ConvertAll
instead.
sbyte[] signed = Array.ConvertAll(unsigned, b => unchecked((sbyte)b));
