微软的新的.NET平台为开发者带来了许多新的诸如GDI+、Globalization之类的编程机制，同时还发明了一门全新的类似Java的编程语言－C＋＋。对于这些新知识，我们应尽快了解、掌握并试图运用到实践项目中去，而通过实例学习的方法无疑是一个非常有效的途径。本文就通过一个简单的实例，向大家展示了在Visual C#中如何运用GDI+和Unsafe代码类等技术以实现简单的数字图像处理。 -Microsoft's new.NET platform for developers to bring as many new GDI, Globalization like programming mechanism, and also invented a new Java-like programming language-C + +. These new knowledge, we should understand, grasp and tried to apply it in practice projects, and through the example of learning is a very effective way. This paper through a simple example to illustrate the Visual C# and how to use GDI Unsafe code for such technology to achieve simple digital image processing.
