The CLI is a specification published by Ecma International, which defines the rules that a development infrastructure must follow in order to provide cross-language compatibility and platform independence. ” The CLR is more than just a virtual execution system; it also provides services such as memory management, code safety verification, security and a strict system of data typing, the common type system (CTS). The just-in-time (JIT) compiler that translates intermediate language (IL) into CPU-specific assemblies is also part of the CLR.
Table 3-3 lists the functions available for explicit conversions. Table 3-3. qxd 2/15/07 9:32 PM Page 35 CHAPTER 3 ■ VB SYNTAX Casting variables with either of these methods is pretty straightforward, as this code snippet shows: Dim StringValue As String = "123" Dim IntegerValue As Integer IntegerValue = CInt(StringValue) Deciding whether to use the conversion functions or the Convert class methods is strictly a matter of style. The Convert class makes code more consistent with data type conversions in C#, which doesn’t have functions such as CStr.
The process of compiling IL into platform-specific instructions is called JIT compiling. exe on a standard Windows computer, the CLR JIT compiler compiles the IL into instructions for the architecture being used. Needless to say, if your code relies on platform-specific libraries or calls any platform-specific APIs, it will only run on that particular architecture. JIT compiling means only a one-time performance hit, however, this performance hit is incurred each time you run your application. The way JIT works, only the code being executed is compiled, and the loader creates a stub for any unused methods.
