CodeDom – An Advance Strategy For Code Generation at Run Time

CodeDom, which stands for Code Doc Object Product, is a single advance method provided by Microsoft.Internet Framework to make code at run-time. qr codes At application degree, it offers programmers the capability to compose a solitary language-unbiased code that can emit source code in a distinct language for later demands.

Code Document Object Design lies inside of the System.CodeDom namespaces of the.Web Framework. The CodeDom has the adhering to benefits:

From a single code that makes use of the CodeDom to represent the framework of resource code that can generate source code of any language supports the CodeDom specification.

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

It provides a language unbiased item design for symbolizing the composition of supply code in memory.
It functions as a resource code translator among various languages.

Common usages of the CodeDOM include:

Creating template code for emitting code wizards, coding examples, XML Internet companies customer proxies, etc.

Dynamically compiling code in languages supported.
T4 (Textual content Template Transformation Toolkit) is yet another potent generation tool presented by Microsoft.web Framework. As opposed to the CodeDom, T4 uses string concatenation to generate textual template to produce code. A great deal of the output code will be place into template blocks, in buy to make the code generator straightforward to generate and customise. Nonetheless, T4 is a language dependent and will need to have a separate code generator for every single output language. On the other hand, the CodeDom enables builders use a one supply code to create the exact same thing in various languages, which obviously give a large benefit in creating.Internet Framework equipment.

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” lessons like the CodeSnippetCompileUnit, CodeSnippetExpression, CodeSnippetStatement, and CodeSnippetTypeMember can be utilized as generic representation. For creating code in a certain language, a corresponding CodeDomProvider course will be needed.

At present there are Microsoft.CSharp.CSharpCodeProvider and Microsoft.VisualBasic.VBCodeProvider that can be utilised to generate C Sharp code and VisuaBasic.web code. Other programming languages will not have CodeDomProvider nevertheless, and may possibly not have simple techniques to depict some CodeDom constructions (delegates, enums, templates, and framework) owing to big difference in language requirements. Nonetheless, generating a CodeDomProvider is not a really complex activity, if the enter CodeDom composition is restricted. Programmers can often build a CodeDomProvider for a particular language by inheriting from CodeDomProvider, and throw exceptions if the building is as well tough to symbolize.
