Advantages of Managed Code
Microsoft intermediate language shares with Java byte code the idea that it is a low-level language with a simple syntax (based on numeric codes rather than text), which can be very quickly translated into native machine code. Having this well-defined universal syntax for code has significant advantages.
Platform independence
First, it means that the same file containing byte code instructions can be placed on any platform; at runtime the final stage of compilation can then be easily accomplished so that the code will run on that particular platform. In other words, by compiling to IL we obtain platform independence for .NET, in much the same way as compiling to Java byte code gives Java platform independence.
You should note that the platform independence of .NET is only theoretical at present because, at the time of writing, a complete implementation of .NET is only available for Windows. However, there is a partial implementation available (see for example the Mono project, an effort to create an open source implementation of .NET, at www.go-mono.com/).
托管代碼的優(yōu)點
Microsoft中間語言與Java字節(jié)代碼共享一種理念：它們都是一種低級語言，語法很簡單(使用數(shù)字代碼，而不是文本代碼)，可以非?？焖俚剞D(zhuǎn)換為內(nèi)部機器碼。對于代碼來說，這種精心設(shè)計的通用語法，有很大的優(yōu)點。
1. 平臺無關(guān)性
首先，這意味著包含字節(jié)代碼指令的同一個文件可以放在任一個平臺中，運行時編譯過程的最后階段可以很容易完成，這樣代碼就可以運行在該特定的平臺上。也就是說編譯為中間語言就可以獲得.NET平臺無關(guān)性，這與編譯為Java字節(jié)代碼就會得到Java平臺無關(guān)性是一樣的。
注意.NET的平臺無關(guān)性目前只是一種可能，因為在編寫本書時，.NET只能用于Windows平臺，但人們正在積極準(zhǔn)備，使它可以用于其他平臺(參見Mono項目，它用于創(chuàng)建.NET的開放源代碼的實現(xiàn)，參見http://www.go-mono.com/)。
