C# 里怎样得到当前执行的函数名，当前代码行，源代码文件名

转自：http://blog.csdn.net/21aspnet/article/details/3522152

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());
