C# Blueprint Action Pattern

Software pattern is the solution of some fixed issues in software development. And it improves the development efficiency. This paper raises the concept of C# blueprint pattern based on a wealth of program model examples. And the formalized definition framework of C# blueprint action pattern is summed up. The framework defines the rules of structure, semantics and so on. At last, examples are raised to explain the C# blueprint action pattern. The raise of C# blueprint provides rapid solutions to C# program modeling and improves the development and maintains efficiency of C# program.
