What tool can be used to implement multi-level parsing of a string (string) and receiving data from it?

Question

C++ / C#

Good day. I will simulate the following situation:
I receive a message that contains the following data:

На С#
Client.GetMessage("MyStatus: " + CurrentStatus);

What tool (in c#) can implement the perception of this string by type:
If the message title = "MyStatus", then accept the following information (CurrentStatus, which also comes in string) and change the CurrentStatus variable to the value that came?

Answer 1

Regular expressions + a bit of logic.
PS
Not only C# but in general...

Answer 2

string.Contains("MyStatus")
