Runtime-generating .Net code for those who have no time
The .Net infrastructure contains built-in code generation (On-the-Fly Code Generation). This allows the .Net program to compile the text written in any programming language and execute the resulting code at the time of its execution itself (without the participation of the programmer). It would be logical to expect that the simplest method of the corresponding class is provided for the implementation of these actions in the standard .Net library. But unfortunately it is not. Microsoft, having done a tremendous way of embedding code generation tools on .Net, did not take the very last step towards the simplest needs of programmers. So you have to do this step yourself.
The simplest means offered by Microsoft for solving the described task is the CSharpCodeProvider class, which is included in the .Net standard library. Using this class is not a very difficult task, but nevertheless it would be useful to have a tool that turns the use of code generated on the fly into a trivial task.
The result is a small set of classes, of which

Suppose you need to calculate the value of a numeric expression given in text form. For example, here is such a "12345678 * 9 + 9". In this case, you just need to write the following:
