将参数添加到方法roslyn的开头

Question

你可以帮帮我吗？我是罗斯林的初学者：D

- ＆GT;发送到此树中的number3（数字5）“number3 = 5”

- ＆GT;发送到树编号1（编号2）和编号2（编号2）中的方法“方法（2,2）”

- ＆GT;从此方法返回值“int returnValue = Method（2,2）”

- ＆GT;从number3“int someNumber = number3”返回值

static void Main(string[] args)
        {
            project1();
        }

        public static void project1()
        {
            var tree = CSharpSyntaxTree.ParseText(@"
            class OurService
            {
                int number3;
                int Method(int number1, int number2)
                {
                    return number1 +  number2 + number3;
                }
            }");


            var diagnostics = tree.GetDiagnostics().Where(n => n.Severity == Microsoft.CodeAnalysis.DiagnosticSeverity.Error).FirstOrDefault();

            var root = (CompilationUnitSyntax)tree.GetRoot();

            var methodDeclareted = root.DescendantNodes().OfType<MethodDeclarationSyntax>().FirstOrDefault();
            var parameters = methodDeclareted.ParameterList;

        }

我自己解决了这个问题。我想只添加这个＆＃34; Roslyn是很棒的工具。你可以删除IronPython和Python＆＃34;。我希望将来我会得到一些分数：P因为现在我得到了我的问题-1：P呵呵

public static void TestCodeAnalizer()
        {

            //var scriptOptions = ScriptOptions.Default.WithReferences("Microsoft.CSharp")
            var text = @"using System.Linq; 

            public class Calculator
            {

            public int number3 = 0;

            public static object AddTwoNumbers(int number1, int number2)
            {
                return (number1 + number2);
            }

            public static int AddThreeNumbers(int number1, int number2)
            {
                Calculator calculator = new Calculator();
                return calculator.AddThreeNumbersNonStatic(number1,number2,5);
            }

            public int AddThreeNumbersNonStatic(int number1, int number2, int number3)
            {
                this.number3 = number3;

                return (number1 + number2 + this.number3);

            }";

            var tree = SyntaxFactory.ParseSyntaxTree(text);
            var compilation = CSharpCompilation.Create(

            Type calculator = compiledAssembly.GetType("Calculator");

            //my send parameters :D
            object[] parametersArray = new object[] { 2, 2 };

            //first answer
            MethodInfo evaluate_AddTwoNumbers = calculator.GetMethod("AddTwoNumbers");
            string answer_AddTwoNumbers = evaluate_AddTwoNumbers.Invoke(null, parametersArray).ToString();

            //second answer
            MethodInfo evaluate_AddThreeNumbers = calculator.GetMethod("AddThreeNumbers");
            string answer_AddThreeNumbers = evaluate_AddThreeNumbers.Invoke(null, parametersArray).ToString();


        }
