We can convert a signed int to an "unsigned" long as such: public static final int BITS_PER_BYTE = 8; public static long getUnsignedInt(int x) { ByteBuffer buf = ByteBuffer.allocate(Long.SIZE / BITS_PER_BYTE); buf.putInt(Integer.SIZE / BITS_PER_BYTE, x); return buf.getLong(0);...
int main() { unsigned int x = 65529; int y = (int) x; printf("%d\n", y); unsigned short z = 65529; short zz = (short)z; printf("%d\n", zz); } 65529 -7 Press any key to continue . . . A little more detail. It's all about how signed numbers are stored in memory...

1.Convert.ToInt是数据类型转换成int类型 2. 有三种方法toint16,toint32,toint64 int16-数值范围:-32768 到 32767 int32-数值范围:-2,147,483,648 到 2,147,483,647 int64-数值范围:-9223372036854775808 到 9223372036854775808 3.所以,按需使用吧 ...
