CodeDom, which stands for Code Document Object Product, is 1 progress method supplied by Microsoft.Web Framework to produce code at operate-time. At application stage, it gives programmers the capacity to write a one language-independent code that can emit source code in a distinct language for later on demands.

Code Document Object Product lies within the System.CodeDom namespaces of the.Web Framework. dynamic qr code The CodeDom has the pursuing benefits:

From a solitary code that utilizes the CodeDom to represent the composition of source code that can produce source code of any language supports the CodeDom specification.

The CodeDom permits resource code and assemblies to be designed, compiled, and executed dynamically at runtime.

It offers a language unbiased object design for representing the composition of resource code in memory.
It functions as a supply code translator amid distinct languages.

Typical usages of the CodeDOM incorporate:

Making template code for emitting code wizards, coding examples, XML Net services shopper proxies, etc.

Dynamically compiling code in languages supported.
T4 (Text Template Transformation Toolkit) is one more potent era instrument provided by Framework. Unlike the CodeDom, T4 employs string concatenation to produce textual template to generate code. A good deal of the output code will be set into template blocks, in buy to make the code generator effortless to produce and personalize. Even so, T4 is a language dependent and will want a different code generator for every output language. On the other hand, the CodeDom allows developers use a one source code to create the same factor in diverse languages, which naturally give a massive advantage in building.Web Framework tools.

Most programing constructs, such as declarations, statements, arrays, casts, iterations, mistake handling and other folks, is supported by the CodeDom. For programing constructs that are not presently supported in CodeDom, “snippet” lessons which includes the CodeSnippetCompileUnit, CodeSnippetExpression, CodeSnippetStatement, and CodeSnippetTypeMember can be used as generic representation. For producing code in a distinct language, a corresponding CodeDomProvider course will be needed.

At present there are Microsoft.CSharp.CSharpCodeProvider and Microsoft.VisualBasic.VBCodeProvider that can be utilized to produce C Sharp code and code. Other programming languages will not have CodeDomProvider nevertheless, and may well not have straightforward approaches to depict some CodeDom constructions (delegates, enums, templates, and framework) thanks to distinction in language specifications. Nevertheless, making a CodeDomProvider is not a extremely intricate process, if the enter CodeDom composition is limited. Programmers can always develop a CodeDomProvider for a specific language by inheriting from CodeDomProvider, and toss exceptions if the construction is as well challenging to symbolize.
