本文介绍在Red Linux 9.0下运行C#程序的方法。先从www.go - mono.org下载相关软件包，接着安装mono，最后进行测试。还给出了测试用的C#代码，包含文件读写操作，如创建文件流、写入日志、读取日志等。

在Red Linux 9.0下运行c#程序:

(1)到www.go-mono.org上,下载软件包

(2)安装mono
# rpm -Uvh *.rpm

        (3)测试
        # mcs test.cs
        # mono test.exe

        //**********
        //test.cs
        //**********
        using System;
        using System.IO;

        class Directory {
           public static void Main(String[] args) {
              FileStream fs = new FileStream("log.txt", FileMode.OpenOrCreate, F
ileAccess.Write);
              StreamWriter w = new StreamWriter(fs);
              w.BaseStream.Seek(0, SeekOrigin.End);   // Set the file pointer to
the end.

Log ("Test1", w);
Log ("Test2", w);

w.Close(); // Close the writer and underlying file.

fs = new FileStream("log.txt", FileMode.OpenOrCreate, FileAccess.R
ead);

              StreamReader r = new StreamReader(fs);
              r.BaseStream.Seek(0, SeekOrigin.Begin);
              DumpLog (r);
           }

           public static void Log (String logMessage, StreamWriter w) {
              w.Write("Log Entry : ");
              w.WriteLine("{0} {1}", DateTime.Now.ToLongTimeString(), DateTime.N
ow.ToLongDateString());
              w.WriteLine(":");
              w.WriteLine(":{0}", logMessage);
              w.WriteLine ("-------------------------------");
              w.Flush();
           }

           public static void DumpLog (StreamReader r) {
              while (r.Peek() > -1) { // While not at the end of the file, write
to standard output.
                Console.WriteLine(r.ReadLine());
              }

}

              r.Close();
           }
        }
