Can dapper deserialize json stored as text?

问题

public class MyType
{
    public int Id { get; set;}
    public int[] MyArray { get; set; }
}

var sql = "SELECT id, MyArrayAsJson as MyArray";
var x = await connection.QueryAsync<MyType>(sql);

I have a string stored in the database which looks like json: [1,2,3,4,5]

When I query the db with Dapper, I would like dapper to deserialize to an object, MyType. Dapper wants MyArrayAsJson to be a string because it is, but I want it to deserialize to an int array. Is this possible?

回答1:

Dapper wants nothing to do with your fancy serialization shenanigans :) Basically, no: read it from the database as a string, then deserialize.

Adding an API that provided more direct / raw access to the incoming data as a BLOB/CLOB sequence would be nice, but it doesn't exist in Dapper today.
