如何使用实体框架将数据库表内容添加到 C# 中的组合框项目？

Question

I want to make a combobox read its items from a table in a database. How should I write the code in Entity Framework v6.x?

Answer 1

Do you need to know how to read data from a database using EF or how to populate combo box items? Or both? Also, it is not clear whether are you using a web, Winforms, WPF, or another technology? I guess you can split these 2 tasks and have 2 functions:

1. Obtaining the items from the database(read about DbContext class)

private List<MyItems> GetItems()
{
    List<MyItems> items = dbContext.Items.ToList();
    return items;
}

2. Populating the combo box function

private void PopulateComboBox(List<MyItems> items)
{
    foreach (var item in items)
    {
        // your code here
    }
}
