CodeDom – An Advance Strategy For Code Technology at Operate Time

CodeDom, which stands for Code Document Object Product, is 1 advance strategy presented by Microsoft.Web Framework to produce code at operate-time. At application stage, it gives programmers the capability to compose a solitary language-unbiased code that can emit resource code in a distinct language for afterwards requirements.

Code Doc Object Design lies inside of the Technique.CodeDom namespaces of the.Net Framework. The CodeDom has the subsequent positive aspects:

From a solitary code that utilizes the CodeDom to represent the composition of source code that can produce source code of any language supports the CodeDom specification.

The CodeDom enables source code and assemblies to be designed, compiled, and executed dynamically at runtime.

It offers a language independent object product for representing the structure of source code in memory.
It acts as a supply code translator among different languages.

Frequent usages of the CodeDOM contain:

Creating template code for emitting code wizards, coding examples, XML Net providers client proxies, etc.

Dynamically compiling code in languages supported.
T4 (Textual content Template Transformation Toolkit) is one more powerful generation tool supplied by Framework. Not like the CodeDom, T4 utilizes string concatenation to develop textual template to produce code. A whole lot of the output code will be set into template blocks, in buy to make the code generator easy to produce and personalize. Even so, T4 is a language dependent and will need to have a independent code generator for every output language. On the other hand, the CodeDom allows developers use a single resource code to make the identical factor in diverse languages, which obviously give a massive edge in building.Net Framework tools.

Most programing constructs, such as declarations, statements, arrays, casts, iterations, error dealing with 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 used as generic representation. For generating code in a specific language, a corresponding CodeDomProvider course will be required.

At present there are Microsoft.CSharp.CSharpCodeProvider and Microsoft.VisualBasic.VBCodeProvider that can be employed to produce C Sharp code and VisuaBasic.web code. Other programming languages don’t have CodeDomProvider nevertheless, and may not have straightforward methods to depict some CodeDom constructions (delegates, enums, templates, and framework) because of to variation in language requirements. Nonetheless, making a CodeDomProvider is not a really intricate activity, if the enter CodeDom framework is limited. dynamic qr codes Programmers can often develop a CodeDomProvider for a distinct language by inheriting from CodeDomProvider, and throw exceptions if the development is as well tough to depict.
