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：
