C# String.Format with '{' character

Question

Can we do a String.Format in a string that contains the '{' character?

Example: String.Format("a{a}a {0} bbb {1}", "val1", "val2");

The a{a}a should be interpreted as part of the string, not as a formatter...

Thanks in advance

It was a typo, I meant to write {1}. – Dante Apr 16 '12 at 20:37 — Dante, Apr 16 '12 at 20:37

Yes. Use two {s, like this:

String.Format("a{{a}}a {0} bbb {1}", "val1", "val2");

Use: {{. By the way, this is answerable from the documentation:

To specify a single literal brace character in format, specify two leading or trailing brace characters; that is, "{{" or "}}".

You should escape { and } with {{ and }}
