CodeDom, which stands for Code Document Object Design, is one advance method provided by Microsoft.Net Framework to make code at operate-time. At application level, it offers programmers the ability to write a single language-unbiased code that can emit supply code in a certain language for afterwards requirements.

Code Document Item Design lies within the System.CodeDom namespaces of the.Net Framework. The CodeDom has the following positive aspects:

From a single code that utilizes the CodeDom to depict the framework of resource code that can generate supply code of any language supports the CodeDom specification.

The CodeDom enables resource code and assemblies to be developed, compiled, and executed dynamically at runtime.

It provides a language impartial object design for representing the framework of supply code in memory.
It acts as a resource code translator among various languages.

Frequent usages of the CodeDOM contain:

Producing template code for emitting code wizards, coding examples, XML Web companies shopper proxies, and so forth.

Dynamically compiling code in languages supported.
T4 (Textual content Template Transformation Toolkit) is yet another effective technology tool presented by Microsoft.net Framework. Unlike the CodeDom, T4 employs string concatenation to develop textual template to generate code. A good deal of the output code will be put into template blocks, in order to make the code generator simple to produce and personalize. Nonetheless, T4 is a language dependent and will require a independent code generator for every single output language. On the other hand, the CodeDom permits developers use a single source code to make the exact same thing in distinct languages, which naturally give a massive advantage in creating.Web Framework instruments.

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

Presently there are Microsoft.CSharp.CSharpCodeProvider and Microsoft.VisualBasic.VBCodeProvider that can be utilized to make C Sharp code and VisuaBasic.internet code. Other programming languages never have CodeDomProvider nevertheless, and may not have basic techniques to depict some CodeDom constructions (delegates, enums, templates, and framework) owing to difference in language technical specs. Nevertheless, producing a CodeDomProvider is not a very intricate activity, if the input CodeDom composition is limited. dynamic qr codes Programmers can often build a CodeDomProvider for a particular language by inheriting from CodeDomProvider, and toss exceptions if the design is as well difficult to represent.
