"Too many characters in character literal error"

Question

I'm struggling with a piece of code and getting the error:

Too many characters in character literal error

Using C# and switch statement to iterate through a string buffer and reading tokens, but getting the error in this line:

case '&&':

case '||':

case '==':

How can I keep the == and && as a char?

Answer 1

This is because, in C#, single quotes ('') denote (or encapsulate) a single character, whereas double quotes ("") are used for a string of characters. For example:

var myChar = '=';  var myString = "=="; 

Answer 2

Here's an example:

char myChar = '|'; string myString = "||"; 

Chars are delimited by single quotes, and strings by double quotes.

The good news is C# switch statements work with strings!

switch (mytoken) {     case "==":         //Something here.         break;     default:         //Handle when no token is found.         break; }
