   Jan 16, 2009 · Otherwise, everytime you marshal a string you’d need to copy it and add the ”. So a string size is 18 + (2 * number of characters) bytes. (In reality, another 2 bytes is sometimes used for packing to ensure 32-bit alignment, but I’ll ignore that). 2 bytes is needed for each character, since .NET strings are UTF-16.

   Aug 9, 2012 · This allows the java.lang.String.substring(int, int) method to operate on O(1) time rather than O(n) time like .NET. The new string returned simply points to the origin string's buffer and the offset is taken into account with all operations. This has the unfortunate side-effect whereby a string of 1 character that is the result of a substring ...

   The GetByteCount method determines how many bytes result in encoding a set of Unicode characters, and the GetBytes method performs the actual encoding. The Encoding.GetBytes method expects discrete conversions, in contrast to the Encoder.GetBytes method, which handles multiple conversions on a single input stream.

   How many byte is a string?

   • So a string size is 18 + (2 * number of characters) bytes. (In reality, another 2 bytes is sometimes used for packing to ensure 32-bit alignment, but I’ll ignore that). 2 bytes is needed for each character, since .NET strings are UTF-16. Thus, a string like so: String mySimpleString = “Hello”; Will be 18 + (2 * 5) = 28 bytes. Splendid.

   How many bytes does an empty string use?

   • So in total, an empty string uses 40 bytes. If the String contains, say, 19 characters, then the String object itself still requires 24 bytes. But now the char array requires 12 bytes of header plus 19*2=38 bytes for the seventeen chars. Since 12+38=50 isn't a multiple of 8, we also need to round up to the next multiple of 8 (56).

   How many byte is a char array if a string has no characters?

   • another int for the cached calculation of the hash code. This means even if the string contains no characters, it will require 4 bytes for the char array reference, plus 3*4=12 bytes for the three int fields, plus 8 bytes of object header. This gives 24 bytes (which is a multiple of 8 so no "padding" bytes are needed so far).
