How to escape braces (curly brackets) in a format string in .NET

Question

How can brackets be escaped in using string.Format.

For example:

String val = \"1,2,3\"
String.Format(\" foo {{0}}\", val); 
         


        

Answer 1

Almost there! The escape sequence for a brace is {{ or }} so for your example you would use:

string t = "1, 2, 3";
string v = String.Format(" foo {{{0}}}", t);
