C# 动态获取代码所在行号

通过system.diagnostics.stacktrace获取代码所在行号和文件信息

获取行号信息

        /// <summary>
        /// get line number of code dynamically
        /// </summary>
        /// <param name="skipframes">number of frames to skip</param>
        /// <returns>line number of code after skipping frames</returns>
        public static int getcodelinenum(int skipframes)
        {
            stacktrace st = new stacktrace(skipframes, true);
            stackframe fram = st.getframe(0);
            int linenum = fram.getfilelinenumber();
            return linenum;
        }

skipframes == 0 ：

获取的是 system.diagnostics.stacktrace st = new system.diagnostics.stacktrace(skipframes, true); 所在行号

skipframes == 1：

获取的是函数getcodelinenum被调用时所在行号

获取文件路径信息

        /// <summary>
        /// get file name information of code dynamically
        /// </summary>
        /// <param name="skipframes">number of frames to skip</param>
        /// <returns>file name information of code after skipping frames</returns>
        public static string getcodefilename(int skipframes)
        {
            stacktrace st = new stacktrace(skipframes, true);
            stackframe fram = st.getframe(0);
            string source = fram.getfilename();
            return source;
        }

获取exception中行号

int linenum = ex.stacktrace.indexof("行号");
