我为 XML 反序列化创建了以下类：

[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true)]
[System.Xml.Serialization.XmlRootAttribute(Namespace = "", IsNullable = false)]

我想创建 2 个绑定源，一个用于 datagridview，一个用于文本框。我尝试了以下方法：

        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";

该程序无法在 bsV.DataMember = "ItemElementName" 行运行。请有任何建议

改变：

bindingsource.DataSource = pc;

到： 

bindingsource.DataSource = new List { pc };

我不知道为什么，但 PropertyManager 不喜欢链接属性，但 CurrencyManager 喜欢。使用 IEnumerable 将欺骗并强制 BindingContext 创建 CurrencyManager 而不是用于绑定单个对象的 PropertyManager。该问题与 BindingSource 无关，您可以将网格的 DataSource 属性设置为列表，将 DataMember 设置为 Preferences。

您也不必使用 BindingSource 绑定到文本框。

只需使用：

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

至于 Value.Maximum 的使用：

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