raspberry pi - shell script that takes a string input by the user and outputs the number of characters in it? -

-

Can you show me a shell script that takes string input by the user and outputs the number of characters in it? I've tried many times but I can not get it right.

Use wc functions like this:

Echo-N ABC | Wc -c

or 

  echo -n abc. Wc -m

- Check the manual for the last press Newline which will be counted as an additional character

c# - XML serialize base class without knowing derived class -

-
I know that a XmlSerializer throws an exception if the type passed does not match the type Since then the serializer was created My question is: Is it possible to serial the base type without knowing the derivative type? Consider the following scenario: The following classes are in a top-level domain and there is no dependency : Public Class Serializer {Private Static String Serialize (base basedata) {var serializer = New XML serializer (typefile); Var sb = new stringbilder (); (Var author = XmlWriter.Create (sb)) using {serializer.Serialize (author, bassadata); } Return sb.ToString (); } Private static string Deserialize (...) {...}} Public class base {public string name {get; Set; }} The following derivative classes have additional dependencies on things like UI components, structure, etc. (and more on this later): [Export (Typ (IMyComponent)] Public category was created: Base, IMyComponent, INotifyPropertyChanged {public new string name {get {return base.Name; ...
