 Customer Request Message......
[[REQUEST_Data]]
KEY=VALUE
KEY=VALUE
KEY=VALUE
[[/REQUEST_Data]]

After replacing the content would become Customer Request Message...... All the content between [[REQUEST_Data]] [[/REQUEST_Data]] must be replaced with empty string and also both the tag is also replace with empty string.

Answer 1

var replaced = Regex.Replace(input, regex, "");
