CodeDom – An Progress Method For Code Generation at Operate Time

CodeDom, which stands for Code Document Item Design, is one particular advance strategy offered by Microsoft.Internet Framework to generate code at operate-time. At software stage, it presents programmers the functionality to write a solitary language-impartial code that can emit resource code in a specific language for afterwards demands.

Code Doc Object Design lies within the Method.CodeDom namespaces of the.Web Framework. The CodeDom has the following rewards:

From a one code that utilizes the CodeDom to depict the construction of resource code that can make source code of any language supports the CodeDom specification.

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

It supplies a language impartial object design for symbolizing the composition of supply code in memory.
It functions as a resource code translator among different languages.

Frequent usages of the CodeDOM contain:

Creating template code for emitting code wizards, coding illustrations, XML World wide web solutions consumer proxies, and so forth.

Dynamically compiling code in languages supported.
T4 (Text Template Transformation Toolkit) is another strong generation instrument provided by Microsoft.internet Framework. Unlike the CodeDom, T4 uses string concatenation to develop textual template to generate code. A whole lot of the output code will be place into template blocks, in purchase to make the code generator straightforward to create and personalize. Nonetheless, T4 is a language dependent and will need to have a different code generator for each and every output language. On the other hand, the CodeDom permits developers use a single supply code to make the exact same thing in various languages, which obviously give a huge advantage in developing.Internet Framework equipment.

Most programing constructs, such as declarations, statements, arrays, casts, iterations, mistake handling and others, is supported by the CodeDom. For programing constructs that are not presently supported in CodeDom, “snippet” lessons including the CodeSnippetCompileUnit, CodeSnippetExpression, CodeSnippetStatement, and CodeSnippetTypeMember can be used as generic representation. For making code in a particular language, a corresponding CodeDomProvider class will be required.

Presently there are Microsoft.CSharp.CSharpCodeProvider and Microsoft.VisualBasic.VBCodeProvider that can be utilised to create C Sharp code and code. Other programming languages will not have CodeDomProvider but, and may not have straightforward approaches to symbolize some CodeDom constructions (delegates, enums, templates, and framework) thanks to variation in language technical specs. Nevertheless, producing a CodeDomProvider is not a really sophisticated activity, if the enter CodeDom structure is restricted. generate qr code Programmers can always construct a CodeDomProvider for a distinct language by inheriting from CodeDomProvider, and toss exceptions if the development is as well hard to represent.
