如何在EF-Core MigrationSqlGenerator中获取Generate函数生成的SQL命令？

using Microsoft.EntityFrameworkCore.Migrations;
using Microsoft.EntityFrameworkCore.Migrations.Operations;
using Microsoft.EntityFrameworkCore.Storage;
using Microsoft.EntityFrameworkCore.Update;

public class CustomMigrationSqlGenerator : MigrationSqlGenerator
{
    private readonly IMigrationsSqlGenerator _migrationsSqlGenerator;
    private readonly IRelationalCommandBuilderFactory _commandBuilderFactory;

    public CustomMigrationSqlGenerator(
        MigrationsSqlGeneratorDependencies dependencies,
        IMigrationsSqlGenerator migrationsSqlGenerator,
        IRelationalCommandBuilderFactory commandBuilderFactory)
        : base(dependencies)
    {
        _migrationsSqlGenerator = migrationsSqlGenerator;
        _commandBuilderFactory = commandBuilderFactory;
    }

    public override IReadOnlyList<MigrationCommand> Generate(
        IReadOnlyList<MigrationOperation> operations,
        IModel model)
    {
        var commands = base.Generate(operations, model);

        foreach (var command in commands)
        {
            var relationalCommand = _commandBuilderFactory
                .Create()
                .Append(command.CommandText)
                .Build();

            var sql = relationalCommand.CommandText;
            // 在这里可以对生成的SQL命令进行处理，比如打印输出或保存到文件

        return commands;
    }
}
