CodeDom – An Advance Strategy For Code Generation at Run Time

CodeDom, which stands for Code Doc Item Product, is one particular advance strategy offered by Microsoft.Net Framework to produce code at run-time. At application level, it presents programmers the functionality to publish a solitary language-impartial code that can emit supply code in a specific language for later on specifications.

Code Document Item Product lies inside of the Method.CodeDom namespaces of the.Net Framework. The CodeDom has the subsequent positive aspects:

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

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

It provides a language unbiased item product for symbolizing the framework of resource code in memory.
It acts as a supply code translator among diverse languages.

Typical usages of the CodeDOM consist of:

Generating template code for emitting code wizards, coding examples, XML World wide web providers consumer proxies, and many others.

Dynamically compiling code in languages supported.
T4 (Text Template Transformation Toolkit) is yet another potent generation resource provided by Framework. In contrast to the CodeDom, T4 employs string concatenation to generate textual template to produce code. A good deal of the output code will be set into template blocks, in order to make the code generator simple to create and customise. Nevertheless, T4 is a language dependent and will want a different code generator for each and every output language. dynamic qr codes On the other hand, the CodeDom enables builders use a solitary supply code to produce the same issue in various languages, which clearly give a massive gain in developing.Web Framework equipment.

Most programing constructs, which includes 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” classes including the CodeSnippetCompileUnit, CodeSnippetExpression, CodeSnippetStatement, and CodeSnippetTypeMember can be utilised as generic illustration. For producing code in a specific language, a corresponding CodeDomProvider course will be necessary.

Presently there are Microsoft.CSharp.CSharpCodeProvider and Microsoft.VisualBasic.VBCodeProvider that can be employed to create C Sharp code and VisuaBasic.web code. Other programming languages never have CodeDomProvider yet, and might not have easy ways to symbolize some CodeDom constructions (delegates, enums, templates, and framework) thanks to distinction in language requirements. However, generating a CodeDomProvider is not a very sophisticated activity, if the enter CodeDom structure is restricted. Programmers can often create a CodeDomProvider for a specific language by inheriting from CodeDomProvider, and throw exceptions if the construction is also challenging to signify.
