CodeDom – An Advance Strategy For Code Generation at Run Time


CodeDom, which stands for Code Doc Item Model, is one progress approach supplied by Microsoft.Internet Framework to make code at run-time. At software degree, it gives programmers the capability to publish a solitary language-unbiased code that can emit supply code in a distinct language for later specifications.

Code Document Item Product lies inside of the Technique.CodeDom namespaces of the.Web Framework. The CodeDom has the pursuing rewards:

From a one code that utilizes the CodeDom to symbolize the structure of source code that can make source code of any language supports the CodeDom specification.

The CodeDom allows source code and assemblies to be developed, compiled, and executed dynamically at runtime.

It supplies a language impartial item model for symbolizing the framework of supply code in memory.
It functions as a source code translator between various languages.

Common usages of the CodeDOM contain:

Generating template code for emitting code wizards, coding illustrations, XML Internet companies consumer proxies, and so on.

generate qr code Dynamically compiling code in languages supported.
T4 (Text Template Transformation Toolkit) is another powerful technology resource presented by Framework. Not like the CodeDom, T4 uses string concatenation to generate textual template to create code. A lot of the output code will be place into template blocks, in purchase to make the code generator easy to generate and customise. Nonetheless, T4 is a language dependent and will require a separate code generator for each and every output language. On the other hand, the CodeDom enables builders use a one resource code to make the exact same point in different languages, which naturally give a large benefit in developing.Internet Framework tools.

Most programing constructs, such as declarations, statements, arrays, casts, iterations, mistake dealing with and other people, is supported by the CodeDom. For programing constructs that are not presently supported in CodeDom, “snippet” classes including the CodeSnippetCompileUnit, CodeSnippetExpression, CodeSnippetStatement, and CodeSnippetTypeMember can be utilised as generic representation. For creating code in a distinct language, a corresponding CodeDomProvider class will be essential.

At the moment there are Microsoft.CSharp.CSharpCodeProvider and Microsoft.VisualBasic.VBCodeProvider that can be used to produce C Sharp code and VisuaBasic.internet code. Other programming languages do not have CodeDomProvider nevertheless, and may not have basic techniques to symbolize some CodeDom constructions (delegates, enums, templates, and framework) thanks to big difference in language specs. Nonetheless, making a CodeDomProvider is not a really complicated process, if the input CodeDom framework is limited. Programmers can constantly build a CodeDomProvider for a distinct language by inheriting from CodeDomProvider, and toss exceptions if the development is also tough to symbolize.
