如何将列表从ASP.NET Core存储到SQL服务器？

Question

I have this table in my database and I want to store incoming data:

public string Id { get; set; } = default!;
public double? Name { get; set; } = default!;
public string? FamilyName { get; set; } = default!;
public List<Addresses> ClientAddress { get; set; } = default!;

Here is my Addresses class:

public string Id { get; set; } = default!;
public string Address { get; set; } = default!;

Now I want to store in database - how should I do with the list?

public Task<bool> StoreModel(MainModel mainmodel) 
{
     var listtostore = new MainModelEnity()
                           {
                               Name = mainmodel.Name,
                               FamilyName = mainmodel.FamilyName,
                               ClientAddress = //how should I store here? 
                           }
}

I assume you meant to ask how you store a list in a relational database? Because if if it is a file store or NoSql database then it's fairly easy.

However the short answer is, you don't. It's not what a relational database was meant to do. See this Post .

That being said, there are ways around it.

1. Store the list as a string:

    var listString = JsonConvert.Serialize(MyList);

   Then you can store that string in the database easily

2. Save the list as a file on the server, then just store the location of the file in the database.
