Python code to c # reference example,

Python code to c # reference example,

Recently, I am working on converting Pyhton code to c # code. The following cases have been tested in person. Now I want to provide a reference for helpful students:

 

Python | C #

Python	C #
Datetime. datetime. strftime (datetime. datetime. now (), '% Y % m % d % H % M % s ')	DateTime. Now. ToString ("yyyyMMddHHmmss ")
Random. choice ('123 ')	Random. Next (1, 9). ToString ()
Struct. pack ('> I', int (time. time ()))	TimeSpan ts = DateTime. UtcNow-new DateTime (1970, 1, 1, 0, 0, 0, 0 ); Byte [] timeSpanBytes = BitConverter. GetBytes (Convert. ToUInt32 (ts )); If (BitConverter. IsLittleEndian) { Array. Reverse (timeSpanBytes ); }
Binascii. hexlify (AB)	BitConverter. ToString (timeSpanBytes)
Random. randint (0, 100000000 ))	Random random = new Random (DateTime. Now. Millisecond ); Random. Next (0, 100000000)
