C# String Literal: Newline and Quote Examples
Use string literals, which are enclosed in quotes. A string literal is constant.String literal. This is constant string data. String data is created in different ways. We use literals as arguments to methods, or anywhere a string is needed.
With a string literal, characters are stored directly inside the metadata. Fewer indirections (which reduces performance) are needed.
This program contains string literals. The class-level string literals are represented as static or const references. The method-level ones are treated separately in the metadata.Static
Newlines: These are specified with either "\r\n" or just "\n." And tabs are specified with "\t."
Quotes: For quotes, we often use a backslash, but for a verbatim literal (prefixed with @), we use two quotes to mean a quote.
At symbol: Four of the string literals are prefixed with the @ symbol. This is the verbatim string literal syntax.
Tip: The C# compiler allows you to use real newlines in verbatim literals. You must encode quotation marks with double quotes.
C# program that uses string literals
using System;
class Program
{
static string _value1 = "String literal";
const string _value2 = "String literal 2";
const string _value3 = "String literal 3\r\nAnother line";
const string _value4 = @"String literal 4
Another line";
const string _value5 = "String literal\ttab";
const string _value6 = @"String literal\ttab";
static void Main()
{
//
// Execution engine begins here.
//
string test1 = "String literal \"1\"";
const string test2 = "String literal 2";
string test3 = @"String literal ""3""";
const string test4 = @"String literal 4";
//
// Print out the string literals.
//
Console.WriteLine(
"{0}\n{1}\n{2}\n{3}\n{4}\n{5}\n{6}\n{7}\n{8}\n{9}",
_value1, _value2, _value3, _value4, _value5, _value6,
test1, test2, test3, test4);
}
}
Output
String literal
String literal 2
String literal 3
Another line
String literal 4
Another line
String literal tab
String literal\ttab
String literal "1"
String literal 2
String literal "3"
String literal 4
Concat. Concatenating string variables is done at runtime. But if a string variable is constant, the compiler will generate intermediate language with the concatenations removed.
Next: This program appears to concatenate 3 strings. When compiled the IL shows that only one string is used.
string.ConcatC# program that concats string literals
using System;
class Program
{
static void Main()
{
const string a = "Dot ";
const string b = "Net ";
const string c = "Perls";
Console.WriteLine(a + b + c);
}
}
Output

Metadata. String literals are stored in the metadata format. This is defined in the Common Language Specification. It includes a database of tables with headers and rows in all exe files.
Tip: There are several predefined streams in the metadata files, including the #Strings stream and the #US (user strings) stream.
The #US stream is used to store programmer-defined literals. The metadata tables store offsets into this stream. The stream itself is a concatenated series of characters.
Note: The execution engine stores the offsets and tables in memory and then reads a range in the #US stream.
Performance. Before the string literals ever reach the metadata or the intermediate language instructions, the C# compiler applies an optimization called constant folding.
Here: String literal constants are separated and shared. Applying constant folding manually is not required for performance.
Storage: If you use a certain string literal in many places in a program, it is stored only once in the user strings stream.
Thus: We see the compiler technique of constant folding applied to string literals in C# programs.
A summary. String literals are specified with the string verbatim syntax. We use the backslash to escape certain sequences. String literals are constant—they cannot be changed.
