Question

我正在从mongodb数据库中检索数据到gridview，我有一个这样的集合：

{"Name":"myName","Details":"bla bla bla","Notes":["note1","note2","note3"]}
{"Name":"myName","Details":"bla bla bla","Notes":["note1","note2"]}
{"Name":"myName","Details":"bla bla bla","Notes":["note1","note2","note3","note4"]}

我的问题是gridview readind＆＃34; Notes＆＃34;值System.String[]

我正在使用此代码：

Mongo mongo = new Mongo();
mongo.Connect();
var db = mongo.GetDatabase("myDB");
var collection = db.GetCollection<MyCollection>();
var entity = collection.FindAll();
BindingList<MyCollection> entity2 = new BindingList<MongoDBTest.MyCollection>();

foreach (Book item in entity.Documents)
{
    entity2.Add(item);                                
}

GridView1.DataSource = entity2;
GridView1.DataBind();

我怎样才能正确阅读＆＃34; Notes＆＃34;值？

Answer 1

我通过为我的实体Book创建一个类来解决它：

public class Book
{
    public string Name { get; set; }
    public string Details { get; set; }
    public List<string> Notes { get; set; }
    public string NotesStr => String.Join(",", Notes);
}

现在我可以从Notes那样检索NotesStr

Eval("NotesStr")

在gridview单元格中读取String []数组
