    <p>I've been following a guide on Binary Serialization (this one here: <a href="http://www.codeproject.com/Articles/1789/Object-Serialization-using-C" rel="nofollow">http://www.codeproject.com/Articles/1789/Object-Serialization-using-C</a>) and I think I finally almost have it working. When I save the file is created, but when I try to load, nothing is loaded. I feel like I'm close to getting this working. Any advice would be appreciated. Here's the code:</p> <p>Save/Load class</p> <pre><code>[Serializable()] public class SaveLoad : ISerializable { public int GameDay = Date.GameDay; public List&lt;Adventurer&gt; Adventurers = FormMain.AdventurerManager.AdventurerList; public SaveLoad() { GameDay = 0; Adventurers = null; } public SaveLoad(SerializationInfo info, StreamingContext ctxt) { GameDay = (int)info.GetValue("Date", typeof(int)); Adventurers = (List&lt;Adventurer&gt;)info.GetValue("Adventurers", typeof(List&lt;Adventurer&gt;)); } public void GetObjectData(SerializationInfo info, StreamingContext ctxt) { info.AddValue("Date", GameDay); info.AddValue("Adventurers", Adventurers); } } </code></pre> <p>Save/Load methods:</p> <pre><code> void btnSaveGame_Click(object sender, EventArgs e) { SaveLoad save = new SaveLoad(); Stream stream = File.Open("SaveGame.osl", FileMode.Create); BinaryFormatter bformatter = new BinaryFormatter(); bformatter.Serialize(stream, save); stream.Close(); } void btnLoadGame_Click(object sender, EventArgs e) { SaveLoad load = new SaveLoad(); Stream stream = File.Open("SaveGame.osl", FileMode.Open); BinaryFormatter bformatter = new BinaryFormatter(); load = (SaveLoad)bformatter.Deserialize(stream); stream.Close(); Date.CalculateDate(); this.Visible = false; ((FormMain)(this.ParentForm)).ControlMainScreen.Visible = true; } </code></pre>

    1. CODo you get `null`? Or do you get an instance both `GameDay` and `Adventurers` are `null`? I noticed, when you are loading, you create a new instance of `SaveLoad` but a few lines done you create another one by deserializing. Perhapse you looked in the wrong instance?

    2. COI figured that was the case. in the tutorial GetObjectData is never called and I'm guessing that's what's wrong. What needs to happen for it to work?

    3. CO@MartinMulder When I click on the load game button, the screen goes back to the main screen, but that's all that happens. Either Load does nothing or save doesn't save properly.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
