CodeDom – An Progress Approach For Code Generation at Run Time

CodeDom, which stands for Code Doc Object Design, is a single advance strategy provided by Microsoft.Internet Framework to produce code at run-time. At software degree, it presents programmers the capacity to publish a single language-impartial code that can emit source code in a specific language for later needs.

qr codes Code Document Item Design lies inside the System.CodeDom namespaces of the.Internet Framework. The CodeDom has the subsequent benefits:

From a solitary code that makes use of the CodeDom to represent the composition of supply code that can generate supply code of any language supports the CodeDom specification.

The CodeDom makes it possible for source code and assemblies to be designed, compiled, and executed dynamically at runtime.

It gives a language unbiased item model for representing the construction of source code in memory.
It acts as a source code translator amongst various languages.

Frequent usages of the CodeDOM contain:

Creating template code for emitting code wizards, coding examples, XML Internet solutions client proxies, etc.

Dynamically compiling code in languages supported.
T4 (Text Template Transformation Toolkit) is an additional potent technology instrument offered by Framework. Not like the CodeDom, T4 uses string concatenation to create textual template to generate code. A lot of the output code will be set into template blocks, in purchase to make the code generator straightforward to create and customise. However, T4 is a language dependent and will need to have a individual code generator for each output language. On the other hand, the CodeDom allows builders use a solitary supply code to create the same point in various languages, which naturally give a massive gain in building.Web Framework tools.

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

At present there are Microsoft.CSharp.CSharpCodeProvider and Microsoft.VisualBasic.VBCodeProvider that can be used to make C Sharp code and code. Other programming languages do not have CodeDomProvider but, and might not have straightforward techniques to depict some CodeDom constructions (delegates, enums, templates, and framework) thanks to distinction in language requirements. Even so, making a CodeDomProvider is not a very intricate activity, if the enter CodeDom framework is restricted. Programmers can often develop a CodeDomProvider for a particular language by inheriting from CodeDomProvider, and throw exceptions if the building is as well tough to represent.
