Compile as: "gcc -o caller caller.c" and "gmcs main.cs".
Then run: ./caller
Adjust the path to 'mono' (or use another exec* that searches in PATH).

The result will be an empty "test-file.log" or an exception, depending on the
version of mono.

----caller.c--------------
#include <unistd.h>

int
main ()
{
        close (0);
        close (1);
        close (2);
        return execlp ("/opt/mono/bin/mono", "/opt/mono/bin/mono", "main.exe",
NULL);
}
-------------------------
------main.cs------------
using System;
using System.IO;

class Seomething
{
        static private int done = 0;
        static StreamWriter log = null;
        public static void mylog(string msg)
        {
                if (done == 0) {
                        log = new StreamWriter("mylogfile.log");
                        done = 1;
                }
                log.Write(msg);
                log.Flush();
        }
        public static void Main(string[] args)
        {
                StreamWriter w = new StreamWriter("test-file.log");
                w.Write("Hello world");
                w.Flush();

                try
                {
                        w.Close();
                }
                catch (Exception e)
                {
                        mylog("StreamWriter.Close() threw exception\n");
                        mylog(e.ToString());
                }
        }
}
