Abstract: When you're programming C# 4.0 and need a little help, this tightly focused and practical book tells you exactly what you need to know -- without long introductions or bloated examples. It's ideal as a succinct quick reference or as a guide to get you rapidly up to speed if you already know Java, C++, or an earlier version of C#. Written by the authors of the acclaimed C# 4.0 in a Nutshell (OReilly), this book covers the entire C# 4.0 language -- without skimping on the details -- including: Features new to C# 4.0, such as dynamic binding, optional and named parameters, and type parameter variance All of C#'s fundamentals Advanced topics, including operator overloading, custom conversions, type constraints, covariance and contravariance, lambda expressions and closures, iterators, nullable types, and operator lifting LINQ, starting with sequences, lazy execution, and standard query operators; finishing with a complete reference to query expressions Unsafe code and pointers, custom attributes, preprocessor directives, and XML documentation

Abstract: The invention provides a method for executing a previous command and replacing named parameters and relates to the technical field of running and maintenance. By adopting the method, the previous executed command can be automatically acquired, and meanwhile two parameters of a named parameter and a replaced parameter input by a user can be acquired; through traversal of the previous executed command, the named parameter is replaced by the replaced parameter, and then the whole command is executed. When contextual management operation maintenance work is conducted, the method can remarkably improve the working efficiency.
