How can I format a String in C# where the pattern has brackets? When I run the following statement...
String.Format("Foo { Bar={0} }", this.Bar);
... I receive a runtime exception:
System.FormatException: Input string was not in a correct format.
Should I have to escape the brackets? How to?
Escape the brackets by doubling the brackets like {{ and }}
String.Format("Foo {{ Bar={0} }}", this.Bar);
Try using double curly braces, so it looks like:
String.Format("Foo {{ Bar={0} }}", this.Bar);
Looks like it has already been answered: Escape curly brace '{' in String.Format
This situation is explained on MSDN in the article Composite Formatting - Escaping Braces
Opening and closing braces are interpreted as starting and ending a format item. Consequently, you must use an escape sequence to display a literal opening brace or closing brace. Specify two opening braces ("{{") in the fixed text to display one opening brace ("{"), or two closing braces ("}}") to display one closing brace ("}").
So this should be your solution
String.Format("Foo {{ Bar={0} }}", this.Bar);
