This can be done with Regex.Replace:
string a = " Hello ! {ssd} jksssss"; string b = Regex.Replace(a, "{\w+}", ""); This won't work for "Hi {!#$#@}!", that is left as an excericse :-) Start at this MSDN page for more basic information on regular expressions in .NET.

Remember to add "using System.Text.RegularExpressions;" at the start of your code for this to work.

abc = Regex.Replace(abc, "{\w+}", ""); // error :Unrecognized escape sequence

Yup. Try @"{\w+}" (with the at symbol). That will treat the backslash as a normal character.
One way without using regexp is below:
string a = " Hello ! {ssd} jksssss"; int start = a.IndexOf('{'); int end = a.IndexOf('}', start); if (end > start && start != -1) { a = a.Remove(pos, end-start+1); } answered Dec 24, 2011 at 0:00

You can use the Regex class in System.Text.RegularExpressions, to do the replace. For example:
var a = " Hello ! {ssd} jksssss"; var newString = Regex myRegex = new Regex("{{.+}}", ""); myRegex.Replace(a, ""); EDIT:
If you want to match multiple occurrances of curly braces, and replace each one, use this regular expression instead:
var a = "Hello ! {ssd} jksssss {tasdas}"; Regex myRegex = new Regex("{{[^{]+}}", ""); var newString = myRegex.Replace(a, ""); // a == "Hello ! jksssss "

You can also use Regex.Replace(), if you don´t want to find the specific positions and the content between braces varies.
