How to call base constructor inside constructor depending on some parameter?

Question

How to call base constructor inside constructor depending on parametres? For example:

public SomeConstructor (){
       if(SomeParameter == "something") //here call base("something");
          else //here call base("something else")
}

in my example

SomeParameter

could be for example local computer name.

To explain what am i doing, i want to determine constructor depending on computer name. I am working on MVC project, and i still forget change name of connection string when i'm publishing project on the server. so, i want to specify if computer name == my computer name, then call

:base("DefaultConnection")

otherwise, call for example

:base("ServerConnectionString")

You can't do that way, you can only call as in your latter examples, and even then, both your examples are passing a string and not changing the parameter type, so it seems senseless this way (they're not even different constructors you're calling). You could get away with calling the constructor in the conventional way, and making sure the provided value is the valid one prior to that.

As an off the cuff example, consider the following:

public SomeConstructor() 
  : base(Configuration.ConnectionString) {

}

public static Configuration {
  public static string ConnectionString {
    get { 
      /* some logic to determine the appropriate value */
#if DEBUG
      return ConfigurationManager.ConnectionStrings["DebugConnectionString"]; 
#else
      return ConfigurationManager.ConnectionStrings["ReleaseConnectionString"]; 
#endif
    } 
  }
}
