.NET/SQL中的参数化表名？

using (SqlConnection connection = new SqlConnection(connectionString))
{
    connection.Open();

    using (SqlCommand command = new SqlCommand("SELECT * FROM @tableName", connection))
    {
        command.Parameters.AddWithValue("@tableName", "Users");

        using (SqlDataReader reader = command.ExecuteReader())
        {
            while (reader.Read())
            {
                // 处理查询结果
            }
        }
    }
}

DECLARE @sql NVARCHAR(MAX) = 'SELECT * FROM ' + @tableName;

EXEC sp_executesql @sql;
