CodeDom – An Progress Technique For Code Era at Run Time

CodeDom, which stands for Code Doc Item Model, is 1 progress technique presented by Microsoft.Web Framework to produce code at operate-time. At software stage, it offers programmers the capacity to compose a one language-independent code that can emit resource code in a specific language for later on needs.

Code Doc Object Product lies inside the Method.CodeDom namespaces of the.Net Framework. The CodeDom has the pursuing advantages:

From a single code that makes use of the CodeDom to depict the framework of supply code that can produce supply code of any language supports the CodeDom specification.

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

It provides a language independent object model for representing the composition of supply code in memory.
It acts as a supply code translator amid different languages.

Typical usages of the CodeDOM consist of:

Creating template code for emitting code wizards, coding examples, XML World wide web services client proxies, and so on.

Dynamically compiling code in languages supported.
T4 (Text Template Transformation Toolkit) is another potent era device provided by Framework. Not like the CodeDom, T4 makes use of string concatenation to produce textual template to produce code. A lot of the output code will be place into template blocks, in get to make the code generator easy to develop and customise. Nonetheless, T4 is a language dependent and will require a separate code generator for each output language. On the other hand, the CodeDom allows builders use a single resource code to create the very same factor in diverse languages, which clearly give a enormous advantage in creating.Internet Framework equipment.

Most programing constructs, such as declarations, statements, arrays, casts, iterations, error managing and other people, 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 utilized as generic illustration. For making code in a distinct language, a corresponding CodeDomProvider class will be needed.

Presently there are Microsoft.CSharp.CSharpCodeProvider and Microsoft.VisualBasic.VBCodeProvider that can be used to produce C Sharp code and VisuaBasic.web code. Other programming languages do not have CodeDomProvider yet, and may well not have basic ways to signify some CodeDom constructions (delegates, enums, templates, and framework) because of to big difference in language specifications. Nevertheless, producing a CodeDomProvider is not a extremely intricate job, if the input CodeDom framework is restricted. Programmers can always create a CodeDomProvider for a distinct language by inheriting from CodeDomProvider, and throw exceptions if the building is as well hard to signify. generate qr code
