Default encoding is misleading: .NET uses UTF-8 everywhere (including strings hardcoded in the source code) and UTF-16LE (Encoding.Unicode) to store strings in memory, but Windows actually uses 2 other non-UTF8 defaults: ANSI codepage (for GUI apps before .NET) and OEM codepage (aka DOS standard).

In MSVC# The *.cs files are in UTF-8 BOM by default and string constants in them converted to UTF-16LE at compile time (see @OwnagelsMagic comment), but it is NOT defined as default: many classes like StreamWriter uses UTF-8 as default. arrays, you should use an ArrayList: If you have a byte array from elsewhere, you can use the AddRange function. To check what the default encoding is, use Encoding.Default.WindowsCodePage (1250 in my case - and sadly, there is no predefined class of CP1250 encoding, but the object could be retrieved as Encoding.GetEncoding(1250)). (Refers to newly added bytes by resize, changes their value to match the source array) The second function is similar, but is only used to append 1 byte, not an array.

Android Encoding.Unicode is popular for string representation in memory, because it uses fixed 2 bytes per char, so one can jump to n-th character in constant time at cost of more memory usage: it is UTF-16LE. Could this be sped up even further by the use of the new Span ? I was looking for a way to encode binary fields into strings and decode from string back to byte[]. (Read more about Computer number systems), here we will learn how to work with hexadecimal values in c programming language? class ctypes.

About us How to check whether a string contains a substring in JavaScript? To convert hex string to byte array, you need to first get the length of the given string and include it while creating a new byte array. OEM codepages are only used for console I/O. We are storing "64" in an unsigned char variable (64 is small value and can be stored with in a Byte) and "FAFA" in the int variable. So effectively GUI defaults to UTF-8, process defaults to CP1250 and console defaults to 852. Actually .Net and Windows use UTF-16 internally for strings. How do you convert a byte array to a hexadecimal string, and vice versa? This question has been answered sufficiently many times, but with C# 7.2 and the introduction of the Span type, there is a faster way to do this in unsafe code: Keep in mind that the bytes represent a UTF-16 encoded string (called "Unicode" in C# land). You can't do that. Approach 1: (Using + operator)One method is to create a string variable and then append the byte value to the string variable with the help of + operator.

I solved the uneven length problem by adding a single character that tells me if the original length of the binary array was odd ('1') or even ('0'). std::stringstream stream; stream << std::hex << your_int; std::string result( stream.str() ); You can prepend the first << with << "0x" or whatever you like if you wish..
