CodeDom – An Advance Technique For Code Generation at Run Time

CodeDom, which stands for Code Doc Object Model, is one advance method provided by Microsoft.Net Framework to create code at operate-time. At software amount, it gives programmers the capability to compose a one language-impartial code that can emit resource code in a certain language for later requirements.

Code Doc Object Product lies inside of the Program.CodeDom namespaces of the.Web Framework. The CodeDom has the subsequent benefits:

From a one code that utilizes the CodeDom to signify the framework of source code that can make supply code of any language supports the CodeDom specification.

The CodeDom allows resource code and assemblies to be produced, compiled, and executed dynamically at runtime.

It offers a language unbiased item product for symbolizing the composition of supply code in memory.
It acts as a source code translator amid distinct languages.

Typical usages of the CodeDOM contain:

Making template code for emitting code wizards, coding examples, XML Net solutions client proxies, and so on.

Dynamically compiling code in languages supported.
T4 (Text Template Transformation Toolkit) is another effective technology device offered by Microsoft.net Framework. dynamic qr codes In contrast to the CodeDom, T4 employs string concatenation to generate textual template to make code. A good deal of the output code will be set into template blocks, in get to make the code generator easy to generate and customize. However, T4 is a language dependent and will want a different code generator for each and every output language. On the other hand, the CodeDom permits builders use a one source code to produce the exact same point in various languages, which naturally give a huge gain in establishing.Internet Framework tools.

Most programing constructs, including declarations, statements, arrays, casts, iterations, mistake handling and others, is supported by the CodeDom. For programing constructs that are not presently supported in CodeDom, “snippet” classes which includes the CodeSnippetCompileUnit, CodeSnippetExpression, CodeSnippetStatement, and CodeSnippetTypeMember can be used as generic representation. For producing code in a particular language, a corresponding CodeDomProvider class will be essential.

Presently there are Microsoft.CSharp.CSharpCodeProvider and Microsoft.VisualBasic.VBCodeProvider that can be utilized to create C Sharp code and VisuaBasic.web code. Other programming languages do not have CodeDomProvider nevertheless, and may not have easy approaches to represent some CodeDom constructions (delegates, enums, templates, and framework) due to difference in language technical specs. Nevertheless, producing a CodeDomProvider is not a very complicated activity, if the input CodeDom construction is limited. Programmers can always create a CodeDomProvider for a distinct language by inheriting from CodeDomProvider, and throw exceptions if the design is too tough to represent.
