How Can I Achieve Dynamic Code Evaluation in C# Using the Roslyn Scripting API?

The dynamic code assessment in the c#

Function in JavaScript allows dynamic execution code string, which is particularly useful when processing the attributes of dynamic changes. In C#, you can use the Roslyn script API to implement this function.

eval() Roslyn script API

Roslyn script API provides a powerful framework for dynamic compilation and execution of the C#code. This API does not require traditional re -compilation, which provides greater flexibility and ease of use.

Use Roslyn to dynamically evaluate C#code:

Install the Nuget package "Microsoft.Codeanalysis.scripting".

1. Use to evaluate the basic code expression. For example:

2. CSharpScript.EvaluateAsync()

   For more complicated code execution, use

   <code class="language-csharp"> await CSharpScript.EvaluateAsync("System.Math.Pow(2, 4)");</code>

   . This method allows definition and execution classes and methods:

3. CSharpScript.RunAsync()

   Use Quote the code previously executed:

   <code class="language-csharp"> var script = await CSharpScript.RunAsync(@"
                 class MyClass
                 { 
                     public void Print() => System.Console.WriteLine(1);
                 }");</code>

4. script.ContinueWithAsync() Example

   <code class="language-csharp"> await script.ContinueWithAsync("new MyClass().Print();");</code>

Suppose there is an integer variable

and the attributes such as "Property1", "Property2", "Property3". In order to dynamically perform the operation of the "Property

I " attribute, you can use the following code:

This method allows operations that are specific to attributes based on the i value dynamic.
