What is the difference Between Assignment and Creating Instance of String in C#? -



What is the difference Between Assignment and Creating Instance of String in C#? -

i have sample code.

var charmass = new char[] { 's', 't', 'r' }; string mystring = new string(charmass); string mystring2 = new string(charmass); string mystring3 = "str"; string mystring4 = "str"; bool bb1 = object.referenceequals(mystring, mystring2); bool bb2 = object.referenceequals(mystring, mystring3); bool bb3 = object.referenceequals(mystring3, mystring4);

why bb1 , bb2 false? know equals must show true, because compares values, memory allocation strings? why mystring3 , mystring4 pointing same block of memory in heap mystring , mystring2 not?

c# compiler optimizes same literals point same string instance

msdn:

the intern pool conserves string storage. if assign literal string constant several variables, each variable set reference same constant in intern pool instead of referencing several different instances of string have identical values.

c# string heap

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
