CodeDom, which stands for Code Doc Item Product, is 1 progress approach supplied by Microsoft.Internet Framework to generate code at run-time. At application degree, it gives programmers the ability to write a one language-impartial code that can emit supply code in a specific language for later needs.

Code Doc Item Product lies in the Program.CodeDom namespaces of the.Net Framework. The CodeDom has the adhering to benefits:

From a solitary code that utilizes the CodeDom to symbolize the framework of supply code that can create source code of any language supports the CodeDom specification.

The CodeDom enables source code and assemblies to be created, compiled, and executed dynamically at runtime.

It offers a language impartial object product for symbolizing the structure of source code in memory.
It functions as a source code translator among different languages.

Frequent usages of the CodeDOM incorporate:

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

Dynamically compiling code in languages supported.
T4 (Text Template Transformation Toolkit) is one more effective generation tool provided by Microsoft.net Framework. Not like the CodeDom, T4 makes use of string concatenation to create textual template to make code. A good deal of the output code will be place into template blocks, in get to make the code generator straightforward to develop and customise. However, T4 is a language dependent and will need a different code generator for every output language. On the other hand, the CodeDom permits developers use a solitary resource code to make the exact same thing in diverse languages, which obviously give a enormous gain in developing.Web Framework instruments.

Most programing constructs, which includes declarations, statements, arrays, casts, iterations, error managing 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 employed as generic representation. For making code in a distinct language, a corresponding CodeDomProvider course will be needed.

Currently there are Microsoft.CSharp.CSharpCodeProvider and Microsoft.VisualBasic.VBCodeProvider that can be employed to make C Sharp code and VisuaBasic.net code. Other programming languages don’t have CodeDomProvider yet, and may possibly not have straightforward ways to depict some CodeDom constructions (delegates, enums, templates, and framework) thanks to distinction in language requirements. Even so, making a CodeDomProvider is not a really complex job, if the input CodeDom composition is restricted. Programmers can usually build a CodeDomProvider for a distinct language by inheriting from CodeDomProvider, and throw exceptions if the building is also difficult to signify. dynamic qr codes
