使用BindingSource组件将Windows Forms控件绑定到类型

https://docs.microsoft.com/en-us/dotnet/desktop/winforms/controls/how-to-bind-a-windows-forms-control-to-a-type?view=netframeworkdesktop-4.8

例子

下面的代码经过使用BindingSource组件将DataGridView控件绑定到自定义类型。在运行示例时，您会注意到在用数据填充控件以前，DataGridView的标签列反映了对象的属性。该示例具备一个Add Customer按钮，用于将数据添加到DataGridView控件。当您单击按钮时，新对象将添加到BindingSource中。在现实世界中，数据多是经过调用Web服务或其余数据源得到的。

将BindingSource绑定到一个类型，而后能够对这个BindingSource添加、删除数据
