File IO

Need to input data from file and output data to file

File IO

Hi All,

Is there a way that I can fetch the data from a file and then again put the data back to the file ? The idea here is I need to get some data from the file and then show up that data in some form of game. Let's say for an example I need some project data to be shown.

Any help on this would really be appreciated.

Thanks,
Amruta

Even though the thread is old, I can still help.

using System;
using System.IO;
using System.Runtime.Serialization.Formatters.Binary;

namespace FileOps
{
    public class FileOperations
    {
        public Data Load(string fileName)
        {
            Data output = new Data();
            if (File.Exists(fileName))
            {
                Stream stream = File.Open(fileName, FileMode.Open);
                BinaryFormatter bFormatter = new BinaryFormatter();
                output = (Data)bFormatter.Deserialize(stream);
                stream.Close();
            }
            else
            {
                System.Windows.Forms.MessageBox.Show(fileName + " could not be loaded.");
            }
            return output;
        }

        public bool Save(string fileName, Data data)
        {
            Stream stream = File.Open(fileName, FileMode.Create);
            BinaryFormatter bFormatter = new BinaryFormatter();
            bFormatter.Serialize(stream, data);
            stream.Close();

            return true;
        }
    }
    [Serializable]
    public struct Data
    {
        public string firstName, lastName;
        public short age;
        public Data(string firstName, string lastName, short age)
        {
            this.firstName = firstName;
            this.lastName = lastName;
            this.age = age;
        }
    }
}
