CS-Script Simple Script

The CS-Script allows you to execute either code fragments or entire class(es) definitions. A script can automatically access host types without any restrictions except types visibility (public vs. private).

The CS-Script library provides different overloads of the LoadCode method that evaluates and loads C# code to the current AppDomain. Returns instance of the first class defined in the code.

The following example shows the evaluation of a simple script that contains a Calculator class and then accessing the script members dynamically.

public static void Example1()
{
    string script = @"using System;
        public class Calculator
        {
            public int Add(int a, int b)
            {
                return a + b;
            }

            public int Subtract(int a, int b)
            {
                return a - b;
            }

            public int Multiply(int a, int b)
            {
                return a * b;
            }

            public int Divide(int a, int b)
            {
                return a / b;
            }
        }";

    dynamic calculator = CSScript.Evaluator.LoadCode(script);

    Console.WriteLine("Add(10, 5): {0}", calculator.Add(10, 5));
    Console.WriteLine("Subtract(10, 5): {0}", calculator.Subtract(10, 5));
    Console.WriteLine("Multiply(10, 5): {0}", calculator.Multiply(10, 5));
    Console.WriteLine("Divide(10, 5): {0}", calculator.Divide(10, 5));
}

Let's execute the above code, and you will see the following output.

Add(10, 5): 15
Subtract(10, 5): 5
Multiply(10, 5): 50
Divide(10, 5): 2
