question not clear..

you can use Replace,Trim functions to remove unwanted characters from the string..

You are right, Trim is not very useful here, But not Replace (what is that, inertia of thinking? many do this pointless suggestion, probably without understanding that strings are immutable), but Substring, or, better, Regex. Please see my answer.

Not a question. "any one can help me?" does not count, as the answer ("yes, someone can") is not what you want.

What's the problem? Trim functions is fully described: http://msdn.microsoft.com/en-us/library/system.string%28v=vs.110%29.aspx[^].

However, you don't really need Trim. What you do depends on the set of possible input strings and your requirements to the extraction of data. Showing a single example does not mean specification. You can either use String.Substring or Regular Expressions:
http://en.wikipedia.org/wiki/Regular_expression[^],
http://msdn.microsoft.com/en-us/library/system.text.regularexpressions.regex%28v=vs.110%29.aspx[^].

I'll leave the implementation, which should be quite trivial, for your home exercise.
