XMLデシリアライズ用に次のクラスを作成しました。

datagridview用とtextbox用の2つのバインディングソースを作成したいと思います。私は以下を試しました：

        ProgrammingConfiguration pc = new ProgrammingConfiguration();

        XmlSerializer serializer = new XmlSerializer(typeof(ProgrammingConfiguration));

        //Reading the XML document requires a FileStream.            
        Stream reader = new FileStream(filename, FileMode.Open);

        //Call the Deserialize method to restore the object's state.
        pc = (ProgrammingConfiguration)serializer.Deserialize(reader);

        reader.Close();

        bindingsource.DataSource = pc;
        bindingsource.DataMember = "Preferences";


        bsV.DataSource = bindingsource;
        bsV.DataMember = "ItemElementName";

プログラムは、bsV.DataMember="ItemElementName"の行で実行できませんでした。任意の提案をお願いします

変化する：

bindingsource.DataSource = pc;

に： 

bindingsource.DataSource = new List { pc };

理由はわかりませんが、PropertyManager はプロパティの連鎖が好きではありませんが、CurrencyManager は好きです。IEnumerable を使用すると、単一のオブジェクトをバインドするための PropertyManager ではなく、BindingContext が CurrencyManager を作成し、だまされて強制されます。この問題は BindingSource に関連していません。代わりに、グリッドの DataSource プロパティをリストに、DataMember を Preferences に設定できます。

テキストボックスにバインドするために BindingSource を使用する必要もありません。

単に使用します：

textBox.DataBindings.Add(list, "Preferences.ItemElementName");

Value.Maximum については、次のものが使用されます。

textBoxMaximum.DataBindings.Add(list, Preferences.Value.Maximum);
textBoxMaximum.DataBindings.Add(bindingSource, Value.Maximum);
