如何使用.net核心DBFunction将行作为参数传递给Postgres函数

using Microsoft.EntityFrameworkCore;
using Npgsql.EntityFrameworkCore.PostgreSQL.Metadata.Conventions;
using System.ComponentModel.DataAnnotations.Schema;

public class MyFunctions
{
    [DbFunction("postgres", "my_function")]
    public static int MyFunction(MyEntity entity)
    {
        throw new NotSupportedException();
    }
}

using Microsoft.EntityFrameworkCore;

public class MyDbContext : DbContext
{
    public DbSet<MyEntity> MyEntities { get; set; }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.HasDbFunction(() => MyFunctions.MyFunction(default))
            .HasTranslation(args => new SqlFunctionExpression("my_function", args, true, typeof(int)));
    }
}

using Microsoft.EntityFrameworkCore;

public class MyService
{
    private readonly MyDbContext _dbContext;

    public MyService(MyDbContext dbContext)
    {
        _dbContext = dbContext;
    }

    public int CallMyFunction(MyEntity entity)
    {
        return _dbContext.MyEntities
            .Select(e => MyFunctions.MyFunction(entity))
            .FirstOrDefault();
    }
}
