C# String.Format with '{' character
<p>Can we do a String.Format in a string that contains the '{' character?</p>

<p>Example: <code>String.Format("a{a}a {0} bbb {1}", "val1", "val2");</code></p>

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

<p>Thanks in advance</p>
