Extension method in c# -


this question has answer here:

what difference between following 2 implementaion,if no difference why need extension methods ? (public static list<tsource> tolist<tsource>(this ienumerable<tsource> source);)

1.ienumerable<student> myextension = mtystudent; // "mtystudent colletion"     myextension.tolist();  2.list<student> mystudent= enumerable.tolist(myextension);

there no difference. call same method either way. enumerable.tolist<tsource>(this ienumerable<tsource> source) extension method. static method in enumerable class, can call instance method. extension methods really.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
