Trying to format a string containing a bracket {

   1:  string id = "txtId";            

   2:  StringBuilder sb = new StringBuilder();

   3:   

   4:  //Formatting this line, would give error: Input string was not in a correct format.

   5:  sb.AppendFormat("$("{0}").click(function () { ", id);

   6:   

   7:  sb.Append("$(this).slideUp();");

   8:  sb.Append("});");



The fix
   1:  string id = "txtId";            
   2:  StringBuilder sb = new StringBuilder();
   3:   
   4:  //Adding another bracket, will do the trick
   5:  sb.AppendFormat("$("{0}").click(function () {{ ", id);
   6:   
   7:  sb.Append("$(this).slideUp();");
   8:  sb.Append("});");
