C # uses pointers to assign values of different value types to a byte array

C # pointer manipulation byte array

Demo (Take the value of add short type for example):

// bytes: Destination byte array; offset: The position of the target in the byte array; value: The added type values  Public Static unsafe void Writeint16tobytes (byteint short value) {    fixed (byte * ptr = bytes)    {        * ((short *) (PTR + offset)) = value;    }}

Implementation ideas:

1. Create a pointer to the first byte of a byte array bytes

2. Locate the memory area where value is stored by increasing the offset

3. Convert the region to short (two bytes) size

4. Copy value to the range and complete the assignment of the short type variable to bytes
