Use some of standard string commands -

C#

var givenString =
                "School name is {SchoolName} and school contact number is {SchoolPhone} and email is {SchoolEmail}";
            const string START_CHAR = "{";
            const string END_CHAR = "}";
         var result=new List<string>();
         while (givenString.IndexOf(START_CHAR, System.StringComparison.Ordinal) > -1)
            {
                var startIndex = givenString.IndexOf(START_CHAR, 
             System.StringComparison.Ordinal);
                var endIndex = givenString.IndexOf(END_CHAR, 
                System.StringComparison.Ordinal);

                result.Add(givenString.Substring(startIndex + 1,endIndex-startIndex-1));
                givenString = givenString.Substring(endIndex+1);
            }

Solution 4

C#

{[@a-zA-Z0-9-]*}

will catch all what is inside curly brackets
and is a combination of lower case letters, upper case letters, numbers, dashes and at signs.

Hi, here is straightforward solution for you:

C#

string input = "School name is {SchoolName} and school contact number is {SchoolPhone} and email is {SchoolEmail}";

string[] output = Regex.Matches(input, "{[^{}]*}")
                       .OfType<Match>()
                       .Select(match => match.Value)
                       .ToArray();

The Regex pattern that I used will match everything that begins with '{' and ends with '}' and does not contain those two characters inside of it.
