Roslyn Scripting Evaluate Expression

The CSharpScript class provides various static methods to evaluate your expressions at run-time. The following example evaluates a simple expression 2 + 3 using the EvaluateAsync method.

static async Task EvaluateExample1()
{
    var result = await CSharpScript.EvaluateAsync("2 + 3");
    Console.WriteLine(result);
}

The CSharpScript.EvaluateAsync method is an async method that evaluates the string passed as a parameter and returns its resulting value.

You can also get the strongly-typed evaluation by using the generic version of the same method as shown below.

static async Task EvaluateExample2()
{
    int result = await CSharpScript.EvaluateAsync<int>("4 + 6");
    Console.WriteLine(result);
}
