CodeDom – An Progress Technique For Code Generation at Operate Time

CodeDom, which stands for Code Document Object Product, is one advance method provided by Microsoft.Internet Framework to create code at operate-time. At software stage, it presents programmers the capacity to publish a solitary language-unbiased code that can emit resource code in a distinct language for later on specifications.

Code Doc Item Product lies inside of the Method.CodeDom namespaces of the.Web Framework. dynamic qr code The CodeDom has the following benefits:

From a solitary code that makes use of the CodeDom to represent the framework of source code that can make supply code of any language supports the CodeDom specification.

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

It provides a language unbiased item model for representing the composition of source code in memory.
It functions as a supply code translator between different languages.

Typical usages of the CodeDOM incorporate:

Creating template code for emitting code wizards, coding examples, XML Net solutions consumer proxies, and so forth.

Dynamically compiling code in languages supported.
T4 (Textual content Template Transformation Toolkit) is an additional strong generation resource provided by Microsoft.internet Framework. Not like the CodeDom, T4 makes use of string concatenation to generate textual template to create code. A good deal of the output code will be set into template blocks, in order to make the code generator straightforward to generate and personalize. However, T4 is a language dependent and will need to have a independent code generator for each output language. On the other hand, the CodeDom permits developers use a solitary source code to generate the very same issue in different languages, which certainly give a enormous edge in creating.Net Framework equipment.

Most programing constructs, like declarations, statements, arrays, casts, iterations, mistake managing and other people, is supported by the CodeDom. For programing constructs that are not presently supported in CodeDom, “snippet” classes like the CodeSnippetCompileUnit, CodeSnippetExpression, CodeSnippetStatement, and CodeSnippetTypeMember can be employed as generic representation. For producing code in a particular language, a corresponding CodeDomProvider course will be essential.

Currently there are Microsoft.CSharp.CSharpCodeProvider and Microsoft.VisualBasic.VBCodeProvider that can be employed to generate C Sharp code and VisuaBasic.net code. Other programming languages don’t have CodeDomProvider however, and may not have simple ways to symbolize some CodeDom constructions (delegates, enums, templates, and framework) due to variation in language specs. Nonetheless, generating a CodeDomProvider is not a extremely complicated job, if the enter CodeDom construction is restricted. Programmers can always build a CodeDomProvider for a certain language by inheriting from CodeDomProvider, and throw exceptions if the development is too challenging to depict.
