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());
