C#获得当前执行的函数名、当前代码行、源代码文件名

[日期：2010-10-18 11:40]   来源：.NET中国学习网  作者：admin   [字体：大 中 小]

　　得到函数名：
　　System.Diagnostics.StackTrace  st  =  new  System.Diagnostics.StackTrace();
　　this.Text  =  st.GetFrame(0).ToString();
　　得到代码行，源代码文件名：
　　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());
