Question

我有一个字典列表，我想绑定到C＃winform

中的网格视图

public class Person { 
  Dictionary<string, object> attributes = new Dictionary<string, object>();
  public Dictionary<string, object> Attributes {
    get { return attributes; }
  }
}

List<Person> persons = new List<Person>();
Person person1 = new Person();
person1.Attributes.Add("name", "Ross");
person1.Attributes.Add("address", "Street 1");
persons.Add(person1);
Person person2 = new Person();
person2.Attributes.Add("name", "Tom");
person2.Attributes.Add("address", "Street 2");
persons.Add(person2);

那么我该如何使用这个字典将它绑定到网格视图。它在下面吗？

GridView1.DataSource = persons.Select(x => x.Attributes).ToList();

我想要的是网格将字符串（键）显示为列
例如
名字|地址
罗斯|街1号
汤姆|街2

有可能吗？

Answer 1

GridView1.DataSource = 
persons.Select(p => new 
{name = p.Attributes["name"], address = p.Attributes["address"]});

Answer 2

试试这个

List<Person> persons = new List<Person>();
            Person person1 = new Person();
            person1.Attributes.Add("name", "Ross");
            person1.Attributes.Add("address", "Street 1");
            persons.Add(person1);
            Person person2 = new Person();
            person2.Attributes.Add("name", "Tom");
            person2.Attributes.Add("address", "Street 2");
            persons.Add(person2);

            List<KeyValuePair<string, string>> items = persons.Select(person => new KeyValuePair<string, string>(person.Attributes["name"].ToString(), person.Attributes["address"].ToString())).ToList();

            dataGridView1.DataSource = items;

将字典绑定到GridView
