写了一个文件处理的类:
namespace MPAY2
{
    class FileProcess
    {
        string fileName;
       public FileProcess(string fileName)
        {
            this.fileName = fileName;
        }

        public void CreateFile()
        {
            FileInfo file = new FileInfo(fileName);
            
            if (file.Exists)
                return;
            else
            {
                FileStream stream = null;
                stream = file.Create();
                stream.Close();
            }
        }

        public void DeleteFile()
        {
            FileInfo file = new FileInfo(fileName);
            if (file.Exists)
                file.Delete();

        }
        public void WriteToFile(string s)
        {
            StreamWriter write = new StreamWriter(fileName);
            write.WriteLine(s);
            write.Close();
        }
        public string ReadFromFile()
        {
            string s;
            StreamReader read = new StreamReader(fileName);
            s = read.ReadLine();
            read.Close();
            return s;
        }
    }
}

可是在pocket PC中按如下调用抱异常:NotSupportedException
   FileProcess fp = new FileProcess(@"C:\temp.ini");//在C盘下创建一个temp.ini的文件
   fp.CreateFile();
可是我在控制台下运行却正常.
这是怎么回事???
