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());
