Common Mistakes

Using single quotes instead of double quotes for strings.

Not using quotes at all around the text.

The correct way to create a string literal in C# is by using double quotes. Single quotes are for characters, and unquoted text is invalid. Using new String("Hello") is not valid in C#.

Common Mistakes

Using single quotes instead of double quotes.

Not using @ and escaping backslashes manually.

Verbatim string literals in C# start with @ and use double quotes. They treat backslashes as normal characters, so you don't need to escape them.

Common Mistakes

Using single quotes for strings.

Using invalid escape sequences like \W.

In C#, newline characters in strings are represented by \n inside double quotes. Single quotes are for characters, and \World is invalid escape sequence.

💡 Hint

Common Mistakes

Using single quotes for strings.

Not escaping double quotes inside strings.

Strings use double quotes. To include a double quote inside a string, escape it with a backslash \". Single quotes are for characters, so they are incorrect here.
