C # small end to big Endian Little Endian

second, what is big and small end

The definitions of Big-endian and Little-endian are as follows:
1) Little-endian is the low byte emissions in the memory of the lower address, high-byte emissions at the high address of the memory.
2) Big-endian is the high-bit bytes emitted at the low address of the memory, low bytes emitted in the memory of the higher address.
For example, for example, digital 0x12 34 56 78 is represented in memory:

1) Big-endian mode:

Low address-----------------> High address
0x12 |  0x34 |  0x56 | 0x78

2) Small terminal mode:

Low address------------------> High address
0x78 |  0x56 |  0x34 | 0x12

It can be seen that the big-endian pattern is similar to string storage.

3) Here are two specific examples:

The 16bit wide number of 0x1234 in Little-endian mode (and Big-endian mode) in CPU memory (assuming storage from address 0x4000) is:

Memory address	Small Terminal mode storage content	Store content in big-endian mode
0x4000	0x34	0x12
0x4001	0x12	0x34

32bit wide number of 0x12345678 in Little-endian mode and Big-endian mode) in CPU memory (assuming that the store starts from the address 0x4000) is:

Memory address	Small Terminal mode storage content	Store content in big-endian mode
0x4000	0x78	0x12
0x4001	0x56	0x34
0x4002	0x34	0x56
0x4003	0x12	0x78
