Here's a sample, I wouldn't do this as a rule, but it illustrates the naming by case.

Field variables i.e. _myName are global to the class in which they are declared but since private are not available outside of class
Properties (public) are global to the class in which they are declared.and are available to any thing which consumes this class
Parameters use camel case and are limited in scope to the method

 public class MyClass
    {
        private string _myName;
        public string MyName { get; set; }

        public MyClass(string myName)
        {
            _myName = myName;

            this.GetNewName(myName);
        }

        private void GetNewName(string myName)
        {
            this.MyName = _myName + ":" + myName;
        }
    }
