Jan 3, 2012 · Are you asking how much memory a string object occupies, or how many bytes the representation of a string will occupy when written to a file or sent over a network (i.e. encoded), because those are two completely different questions. majidgeek almost answered the former while diya answered the latter (at least for two common encodings).
Sep 26, 2008 · The theoretical limit may be 2,147,483,647, but the practical limit is nowhere near that. Since no single object in a .NET program may be over 2GB and the string type uses UTF-16 (2 bytes for each character), the best you could do is 1,073,741,823, but you're not likely to ever be able to allocate that on a 32-bit machine.
4 bytes: Stores fractional numbers. Sufficient for storing 6 to 7 decimal digits: double: 8 bytes: Stores fractional numbers. Sufficient for storing 15 decimal digits: bool: 1 bit: Stores true or false values: char: 2 bytes: Stores a single character/letter, surrounded by single quotes: string: 2 bytes per character
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.
Aug 9, 2012 · This made strings at least 4 bytes longer. This field was removed in 4.0. Did you know that in Java, there is a buffer pointer (in C# the buffer comes straight after the string length) and an offset field used to store an offset within the string buffer. This allows the java.lang.String.substring(int, int) method to operate on O(1) time rather ...
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.

Jun 6, 2023 · This property returns an integer representing the number of characters in the string. To use the Length property in C# to retrieve the length of a string, follow these steps: First, declare a string variable: string text = "Hello, World!"; Then, access the Length property with text.Length: int length = text.Length;
