You may use String.Split[^] for the purpose.

Solution 2

You could grab a substring starting from the index of the special character:

C#

string newstring = str.Substring(str.IndexOf(">"));

Or, if it has to be a specified length:

C#

int length = 1;

string newstring = str.Substring(str.IndexOf(">"), length);

There's also a string.LastIndexOf() method which accepts either a string or a char.

Solution 3

Hi,

or do it the Regex way.

C#

string str = "qwertyuiop@345*7%6&n>ABCD";

string pattern = ".*>(?<result>.*)";

Regex regex = new Regex(pattern);

Match match = regex.Match(str);

if (match.Success)
{
    string result = match.Groups["RESULT"].Value;
}

Best regards,
Stephan
