C# 裡怎樣得到當前執行的函數名，當前代碼行，源代碼文件名

得到函數名：

System.Diagnostics.StackTrace st = new System.Diagnostics.StackTrace();
this.Text = st.GetFrame(0).ToString();

得到代碼行，源代碼文件名：

StackTrace st = new StackTrace(new StackFrame(true));
Console.WriteLine(" Stack trace for current level: {0}", st.ToString());
StackFrame sf = st.GetFrame(0);
Console.WriteLine(" File: {0}", sf.GetFileName());
Console.WriteLine(" Method: {0}", sf.GetMethod().Name);
Console.WriteLine(" Line Number: {0}", sf.GetFileLineNumber());
Console.WriteLine(" Column Number: {0}", sf.GetFileColumnNumber());
