C# string manipulation search and replace

Question

I have a string which contain tags in the form < tag >. Is there an easy way for me to programmatically replace instances of these tags with special ascii characters? e.g. replace a tag like "< tab >" with the ascii equivelent of '/t'?

Answer 1

Regex patterns should do the trick.

Answer 2

string s = "...<tab>...";
s = s.Replace("<tab>", "\t");

Answer 3

using System.Text.RegularExpressions;

Regex.Replace(s, "TAB", "\t");//s is your string and TAB is a tab.

Answer 4

public static Regex regex = new Regex("< tab >", RegexOptions.CultureInvariant | RegexOptions.Compiled);
public static string regexReplace = "\t";
string result = regex.Replace(InputText,regexReplace);
