C# 获取调用函数 参数名称和值

StackTrace stackTrace = new StackTrace(); 
ParameterInfo[] parameters = stackTrace.GetFrame(1).GetMethod().GetParameters(); 

如上代码在调用微软的API时，只能获取参数的名称，不能获取参数的值。

在网上找了一个用PostSharp工具来获取函数参数名称和值，经整理代码如下：

  class Program
    {
        static void Main(string[] args)
        {
            string filePath = @"C:\log.txt";
            if (File.Exists(filePath))
            {
                FileStream fs = File.Create(filePath);
                fs.Close();
            }
            Trace.Listeners.Add(new LogTraceListener(filePath));
            Trace.Listeners.Add(new TextWriterTraceListener(Console.Out));

            MyClass my = new MyClass();
            my.MyMethod(44, "asdf qwer 1234", 3.14f, true);
            Console.ReadKey();
        }
    }
    public class MyClass
    {
        public MyClass()
        {
        }
#if DEBUG
        [Trace("DEBUG")]
#endif
        public int MyMethod(int x, string someString, float anotherFloat, bool theBool)
        {
            return x + 1;
        }
    }
    [Serializable]
    public sealed class TraceAttribute : OnMethodBoundaryAspect
    {
        private readonly string category;

        public TraceAttribute(string category)
        {
            this.category = category;
        }

        public string Category { get { return category; } }

        public override void OnEntry(MethodExecutionArgs args)
        {
            Trace.WriteLine(string.Format("{2}----Entering {0}.{1}.",
                                          args.Method.DeclaringType.Name,
                                          args.Method.Name, DateTime.Now.ToString()), category);

            for (int x = 0; x < args.Arguments.Count; x++)
            {
                Trace.WriteLine(args.Method.GetParameters()[x].Name + " = " +
                                args.Arguments.GetArgument(x));
            }
        }

        public override void OnExit(MethodExecutionArgs args)
        {
            Trace.WriteLine("Return Value: " + args.ReturnValue);

            Trace.WriteLine(string.Format("{2}---Leaving {0}.{1}.",
                                          args.Method.DeclaringType.Name,
                                          args.Method.Name, DateTime.Now.ToString()), category);
        }
    }

    public sealed class LogTraceListener : TraceListener
    {
        public string FileName { set; get; }
        public LogTraceListener(string filename)
        {
            FileName = filename;
        }
        public override void Write(string message)
        {
            using (StreamWriter sw = new StreamWriter(FileName, true, Encoding.UTF8, Int16.MaxValue))
            {
                sw.Write(message);
            }
        }

        public override void WriteLine(string message)
        {
            using (StreamWriter sw = new StreamWriter(FileName, true, Encoding.UTF8, Int16.MaxValue))
            {
                sw.WriteLine(message);
            }
        }
    }

运行结果如图：
